The Issue This case presents two questions for consideration. The first question concerns the Petitioners' contention that the grant of the permit at issue must be considered contemporaneously with the matters of file in the application made by the Respondent, The Deltona Corporation, with the Respondent, State of Florida, Department of Environmental Regulation, File No. 64-24208, pending before the Department. From the point of view of the Petitioners, should this contemporaneous review process be afforded, then the current permit would not be granted due to the alleged deficiencies associated with the application, File No. 64-24208. The second question to be answered in this case concerns the dispute between the Respondents on the issue of water quality monitoring as a condition to granting the permit sought herein. The Respondent Department would have the applicant monitor in six lakes in the area of the project and the applicant would restrict its monitoring activity to three lakes in the project area. The Petitioners support the Department in its position on the monitoring question. 1/
Findings Of Fact The Respondent, The Deltona Corporation, has made application with the Respondent, State of Florida, Department of Environmental Regulation, to effect drainage system improvements to a land locked conveyance network which consists of the enlargement and regrading 990 lineal feet of existing channel cross- section and the installation of additional culverts and control structures at road crossings. The project also involves repairs and replacement of a damaged culvert. The work would be accomplished by land based equipment transported to the work site by existing overland routes. The excavated sand fill would be placed on upland property owned by The Deltona Corporation. The details of the project and data related to the geographical area may be found in the Joint Exhibit I admitted into evidence. The date of the application for permit is December 12, 1979. On January 25, 1980, the Department of Environmental Regulation sent out a notice of the pending review by the Department of the permit application. After receipt of that notice, attorney for the Petitioners, on February 12, 1980, wrote to the Department expressing the objection to the project made by property owners in the area of the project site, together with a list of those owners found in an attached Petition of owners' names and addresses. A copy of this letter and attached Petition may be found as Joint Exhibit No. VII admitted into evidence. Subsequent to the receipt of the statement of objections, the Department issued a construction permit dated April 30, 1980, subject to conditions. A copy of this permit may be found as Joint Exhibit No. VIII admitted into evidence. The Petitioners, through their counsel, then filed a formal petition dated May 6, 1980, which was the vehicle utilized in establishing the details of this dispute and was the basis for the Department Secretary forwarding the case to the Division of Administrative Hearings for consideration by a hearing officer in keeping with the provisions of Section 120.57, Florida Statutes. The hearing was conducted on October 16, 1980, and the Petitioners' position was more specifically defined in the course of that hearing and the claim as described in the issue statement of this order constitutes the substance of the Petitioners' position. 2/ Joint Exhibit No. I; petitioners' Exhibit No. 1 and Respondent Deltona's Exhibits 1, 2 and 4 constitute sketches and aerial photographs of the general project area. Joint Exhibit No. 1 identifies the work area with more particularity. Respondent's Exhibit No. 2 indicates the desired flow pattern of the water through the various lake systems and indicates whether the flow is by gravity flow or pump flow. This drawing depicts the proposed channels and structural improvements that would be involved. The Department has indicated that all the regulatory concerns which it has about the project associated with Permit No. 64-26478-4E, the permit in question, have been adequately addressed, subject to the conditions set forth in the permit document. Joint Exhibit Nos. V and VI; Respondent Deltona's Exhibit Nos. 5, 6 and 7; and the Petitioners Exhibit No. 2 are exhibits pertaining to water quality concerns, to include sample results. The testing and other information provided indicates that the project as contemplaced, would meat the regulatory parameters set forth in Chapter 403, Florida Statutes, and Chapters 17-3 and 17-4, Florida Administrative Code. The Department in expressing its concern that continued water quality monitoring be conducted has indicated that it feels that future periodic monitoring should be done in Jenkins Pond, Lake Big, Lake Diana, McGarity Lake, Sidney Lake and Lake Mitnik. The Respondent Deltona would only conduct this monitoring in the first three lakes named. By looking at the Respondent Deltona's Exhibit No. 2, it could be seen that all of the aforementioned lakes would be in the same basic flow pattern. Of the system of lakes, the area around McGarity Lake is the most highly developed and and has the greatest potential for causing unacceptable pollution. That pollution could be carried through the other lakes within the system as described in view of the potential of the system, if the project is built, to convey a greater volume of water at a higher rate of flow. A more expansive water quality monitoring system within six lakes as opposed to three lakes would increase the opportunity to discover potential hazards from pollutant at an earlier data. This is particularly so by using lakes such as McGarity Lake where there is a higher level of developmental build-out.
The Issue The issue is whether the Southwest Florida Water Management District (District) should issue water use permit (WUP) No. 2004912.006 to the City of Lakeland (City), and if so, how much water should be allocated under the permit and what conditions should be imposed on the allocation, particularly in regard to withdrawals from the City's Northeast Wellfield (NEWF).
Findings Of Fact Introduction This is an unusual case in that the District gave notice of its intent to issue a permit that the City does not want and that the District staff testified that the City is not even entitled to based upon the information submitted prior to and at the final hearing. That said, there is no disagreement between the parties that a permit should be issued to the City. Indeed, despite the District Staff's testimony that the City failed to provide “reasonable assurances” prior to or at the final hearing on a variety of issues, the District takes the position in its PRO that a permit should be issued to the City, subject to various conditions and limitations. There is also no disagreement between the parties that the permit should include an allocation of 28.03 mgd from the City’s Northwest Wellfield (NWWF). The main areas of disagreement between the District and the City are the duration of the permit; the total allocation of water under the permit; and, perhaps most significant, the total allocation from the NEWF. Parties The City is an incorporated municipality located in Polk County. The City is within the boundaries of the District and is within the Southern Water Use Caution Area (SWUCA) designated by the District. The City is the applicant for the WUP at issue in this case, No. 20004912.006. The City operates a public water utility that provides potable water and wastewater services to customers in and around the City. The utility’s water service area extends beyond the City limits into surrounding unincorporated areas of Polk County. The District is the administrative agency responsible for conservation, protection, management and control of the water resources within its geographic boundaries pursuant to Chapter 373, Florida Statutes, and Florida Administrative Code Rule Chapter 40D. The District is responsible for reviewing and taking final agency action on the WUP at issue in this case. Stipulated Facts The parties stipulated that the City’s substantial interests have been adversely affected by the District’s intent to issue the proposed permit, and that the proposed permit is different from the permit that the City applied for. The parties also stipulated that there is reasonable assurance that the City’s proposed water use will not interfere with a reservation of water as set forth in Florida Administrative Code Rule 40D-2.302; that the proposed use will not significantly induce saline water intrusion; that the proposed use will incorporate the use of alternative water supplies to the greatest extent practicable; and that the proposed use will not cause water to go to waste. The City’s Wellfields Overview The City obtains the water that its water utility provides to its customers from two wellfields, the NWWF and the NEWF. The NWWF is located north of Lake Parker in close proximity to Interstate 4 and Kathleen Road. It provides water to the Williams Water Treatment Plant, from which the water is distributed throughout the City water utility’s service area. The NWWF is located on the Lakeland Ridge, which is a geographic feature that is approximately 250 to 260 feet above sea level. The Lakeland Ridge has a thick clay intermediate confining unit that isolates the surficial aquifer from the underlying aquifers. The NEWF is located to the north of Interstate 4, adjacent to Old Polk City Road. It provides water to the Combee Water Treatment Plant (Combee), from which the water is distributed throughout the City water utility’s service area. The NEWF is located at an elevation of approximately 135 feet above sea level. The surficial aquifer at the NEWF is relatively thin, and the intermediate confining unit at the NEWF is not as thick as it is at the NWWF. The Upper Floridan Aquifer (UFA) begins at approximately 65 below land surface at the NEWF. The City’s water treatment plants are traditional lime softening plants and are not able to treat brackish groundwater or surface water to the extent necessary for human consumption. It would be cost-prohibitive to implement a process to treat brackish water at the plants. Relevant Permitting History The City’s water utility has been in operation for more than 100 years, and the NWWF has been in operation since at least the early 1980’s. The earliest permit for the NWWF contained in the record is permit No. 204912, which was issued by the District in January 1987. The permit authorized average annual withdrawals of 28.3 mgd, and had an expiration date of January 1993. The NEWF was first permitted by the District in December 1989. The permit, No. 209795.00, authorized the City to pump an average of 9.0 mgd from the NEWF. The permit had a six-year duration, with a December 1995 expiration date. The permits for the NWWF and the NEWF were combined into a single permit in October 1993. The permit, No. 204912.03, authorized the City to pump a total of 28.1 mgd, with 9.0 mgd from the NEWF. The permit had a 10-year duration, with an October 2003 expiration date. In December 2002, the City's WUP was administratively modified pursuant to the District’s SWUCA rules. The modified permit, No. 20004912.004, did not change the permitted quantities at the NEWF or the 2003 expiration date, but the total allocation was reduced to 28.03 mgd. In October 2003, prior to the expiration of the existing permit, the City submitted an application to renew and modify its WUP permit. The application requested a 20-year permit with a total allocation of 32.8 mgd, with up to 16.0 mgd from the NEWF. During the permit review process, the City amended its application to increase the requested total allocation by 4.0 mgd (from 32.8 mgd to 36.8 mgd) and to decrease the requested duration of the permit by five years (from 2023 to 2018). The 36.8 mgd requested by the City was to be allocated between the NWWF (28.03 mgd) and the NEWF (8.77 mgd). The City supplemented its application during the permit review process in response to multiple requests for additional information and clarification from the District. The information provided by the City in support of the application is extensive; the “permit file” received into evidence consisted of approximately 2,500 pages, and the entire file is approximately twice that size.2 The review process culminated in what the District staff considered to be a “negotiated permit”3 that would initially authorize pumping of 33.03 mgd, with 28.03 from the NWWF, 1.5 mgd from the NEWF, and 3.5 mgd from a production well to be constructed at Combee. The proposed permit includes a phasing schedule that would allow for increased withdrawals -- up to 35.03 mgd total and 4.0 mgd from the NEWF4 -- if the City is able to demonstrate to the District’s satisfaction that the increased pumping will not cause adverse environmental impacts. The District gave notice of its intent to issue the proposed permit on December 29, 2006, and the permit was placed on the “consent agenda” for the District Governing Board’s meeting on January 30, 2007. On January 23, 2007, before the proposed permit was considered by the Governing Board,5 the City timely filed a petition challenging the proposed permit. The petition alleges that the proposed permit does not allocate sufficient water to meet the City's projected population demands in 2018 and that it does not allocate water quantities from the NEWF and the NWWF in the manner requested by the City. The NEWF The NEWF is approximately 880 acres in size. Wetlands comprise approximately half of the site. The NEWF is located within the boundaries of the Green Swamp, which is an area of critical state concern (ACSC) designated under Chapter 380, Florida Statutes. The Green Swamp is a hydrologically and environmentally important feature of central Florida encompassing thousands of acres of cypress wetlands, marshes, and forests. In 1992, a task force recommended that public water supply wellfields “of capacity greater than 1.8 mgd (average 3.6 mgd maximum)” from the UFA be discouraged in the Green Swamp ACSC in favor of wells from the Lower Floridan Aquifer in order to “mitigate drawdown impacts to the surficial aquifer system and resulting dehydration of wetlands . . . .” There is no evidence of that recommendation being formally adopted by the District or any other governmental agency, and the District does not have more stringent permitting criteria for WUP applications in the Green Swamp, except that it considers potential adverse impacts to all isolated wetlands and not just those larger than one-half acre in size.6 The City installed five 16-inch production wells at the NEWF, along with a number of associated monitoring wells. The production wells, which are cased to approximately 120 feet with a total depth of approximately 750 feet, pump water from the UFA. Pumping at the NEWF started in October 2005. The City has been pumping 4.0 mgd from the NEWF since that time. The City has spent over $34 million to bring the NEWF into service. The costs directly related to the acquisition of the NEWF site and the installation of the wells at the site account for approximately $7.6 million of that amount; the remainder of the costs are for associated infrastructure, such as the installation of water lines from the NEWF site and the construction of Combee. The wetlands on the NEWF site are predominantly isolated cypress wetlands, although there are some connected systems. Isolated wetlands are more susceptible to impacts from water deprivation than are connected wetland systems. The uplands on the NEWF site consist primarily of open pasture and fields and areas of planted pines. Extensive drainage improvements were constructed on the NEWF site between 1941 and 1980 when the site was being used as improved pastureland for cattle grazing and managed woodland for logging and silviculture. The improvements included the construction of a network of drainage ditches, culverts, roads, a grass landing strip, and a gas pipeline. The intent and effect of the drainage improvements was to remove surface water from the onsite wetlands. Historical aerial photographs show that these efforts were successful. The wetlands on the NEWF were adversely impacted by the drainage improvements, but for the most part, they are still functioning, albeit low-quality wetlands. The extensive ditching on the NEWF site continues to have an adverse impact on the wetlands even though the ditches have not been maintained and do not function as efficiently as they once did. The planted pine trees on the NEWF site may also be adversely affecting the wetlands through increased evapotranspiration from the surficial aquifer. However, the evidence was not persuasive regarding the extent of the impact from evapotranspiration. The present condition of the wetlands at the NEWF is not the result of recent activity. The biological indicators in the wetlands (e.g., adventitious roots on cypress trunks, large oak trees in the wetlands, red maple trees in areas that had at one time been dominated by cypress trees) show that the degraded condition of the wetlands dates back decades. The progressive draining and degradation of the wetlands caused by the ditching and other drainage improvements constructed on the NEWF site is apparent in the historic aerial photographs of the site. The size of the wetlands and the “hydrologic signatures” (e.g., standing water around the rims of wetlands and across the site, extensive cypress canopies, etc.) visible on earlier aerial photographs are less visible or non- existent in more recent aerial photographs. The wetlands on the NEWF site have shown no biological indicators of impacts from the pumping at the NEWF that started in October 2005. This does not necessarily mean that the pumping is not impacting the wetlands because the parties' experts agree that it can take many years for such biological indicators to appear. The more persuasive evidence establishes that the historical drainage improvements on the NEWF site were the primary cause of the degraded condition of the wetlands.7 The more persuasive evidence also establishes that unless altered, the drainage improvements on the NEWF site will continue to have an adverse effect on the wetlands. The City proposed a conceptual Wetland Improvement Plan (WIP) that is designed to restore and enhance the wetlands on the NEWF. A central component of the WIP is the reengineering and alteration of the drainage features by installing “ditch blocks” in some areas and culverts in other areas. The WIP also includes not replanting the pine trees on the NEWF site once the existing planted pines are harvested. The ditch blocks and other modifications to the drainage features are intended to hold water on the NEWF site and redirect it to the wetlands. This will help to hydrate the wetlands, increase soil moisture levels, and allow more water to percolate into the surficial aquifer following rain events. The District staff expressed some concerns with the City’s WIP at the final hearing, but acknowledged that the plan’s “conception . . . has a lot of merit.” Indeed, in its PRO, the District recommends the “installation of ditch blocks and similar measures at the [NEWF] site.” The WIP, if properly implemented, has the potential to enhance the wetlands by returning them to a more natural condition. The City will likely need an Environmental Resource Permit (ERP) from the District before any system of ditch blocks can be installed. The details of the WIP can be worked out during the ERP permitting process.8 A good monitoring plan is part of providing reasonable assurances. The parties agree that a monitoring plan should be included as a permit condition, and the EMMPs attached to the parties’ respective PROs appear to be materially the same. The City has monitored the wetlands at the NEWF since 1994, pursuant to a specific condition in the 1993 WUP permit. The methodology used by the City to monitor the wetlands was approved by the District, and despite the fact that the City has submitted biannual monitoring reports to the District for almost 14 years, the District expressed no concerns regarding the methodology or results of the monitoring until recently. The District commenced its own wetland assessment procedure at the NEWF in May 2007, which included setting “normal pools” in several of the wetlands. “Normal pool” describes the level at which water stands in a wetland in most years for long enough during the wet season to create biological indicators of the presence of water. The establishment of normal pools was part of the District’s efforts to establish the “existing natural system” against which any post-withdrawal adverse impacts at the NEWF would be measured in accordance with Section 4.2 of the Basis of Review for Water Use Permit Applications (BOR).9 Normal pools could not be established in several of the wetlands because there was no measurable standing water above the surface in the wetland. District staff observed similar conditions –- i.e., no standing water in the wetlands –- on at least one occasion following a significant rain event prior to the start of pumping at the NEWF. The District does not have a rule governing the setting of normal pools, but the City’s experts did not take issue with the normal pools set by the District or the methodology used by the District to set the normal pools. The EMMP proposed by the City is an extensive monitoring plan that incorporates a series of onsite monitoring wells, wetland monitoring stations for vegetation and hydrogeology, monitoring of pumping rates and pumping data, and monitoring of rainfall data. The EMMP will make use of the extensive data that has been collected on the NEWF site since the 1990’s as well as the normal pools set by the District, and if properly implemented, the EMMP will detect any potential adverse impacts as they occur to allow for remedial mitigation. The District staff acknowledged at the final hearing that the EMMP proposed by the City “with some minor modifications” is an appropriate plan to monitor changes in the wetlands at the NEWF. The necessary "minor modifications" were not explained at the final hearing, and as noted above, there does not appear to be any material difference in the EMMPs attached to the parties’ respective PROs. The Green Swamp is generally viewed as a “leaky” area, with little or no confinement between the surficial aquifer and the Floridan aquifer. Regional data, including studies by the United States Geologic Survey (USGS) and the District, reflect that the NEWF is located in a “transitional area” between areas of little or no confinement to the north, northwest, and east of the NEWF and areas of thicker confinement to the south. However, at least one study (published in 1977 USGS report) shows the NEWF in an area designated as "poor" for its relative potential for downward leakage. Regional data may be used to gain knowledge about the aquifer properties at a potential well site, but such data is not a valid substitute site-specific data. Indeed, the location of the NEWF in a “transitional area” makes site-specific data even more important. The City used geologic cross-sections (e.g., soil borings and core samples) at the NEWF to determine the site’s lithologic characteristics. By contrast, the District relied primarily on USGS reports and other regional data to postulate as to the lithologic characteristics of the NEWF. As a result, the City’s position regarding the lithologic characteristics of the NEWF was more persuasive than the District’s position. The lithology of the NEWF site consists of a shallow, sandy surficial aquifer, which extends to a depth of 3 to 5 feet, proceeding downward to sandy clay and clay sand semi- confining layers, alternating with impermeable clay units, interspersed with an intermediate aquifer composed of sandy clays and clay sands that contain water, proceeding downward to the limestone of the UFA. The presence of clay layers between the intermediate aquifer and the UFA, together with clay layers between the intermediate aquifer and the surficial aquifer, provide two layers of protection between the pumped aquifer and the surficial aquifer and wetlands, and serve to ameliorate any impacts to the surficial aquifer caused by withdrawals from the UFA. “Leakance” is a measure of vertical conductivity that describes the rate at which water flows through a confining unit. As a result, leakance is one of the most important factors to consider when modeling surficial aquifer impacts and potential wetland impacts from groundwater pumping. Generally, a higher leakance value is an indication of a “leakier” system with less confinement between the surficial aquifer and the UFA. The “leakier” the system, the greater the impacts of pumping on the surficial aquifer will be. The District contends that the confining unit underlying the NEWF is “leaky” and that the pumping at the NEWF is likely to directly and adversely affect the onsite wetlands. However, the more persuasive evidence establishes that the lower leakance value derived by the City based upon the site-specific lithology of the NEWF and the data from the aquifer performance tests (APTs) conducted at the NEWF is more accurate than the higher leakance value urged by the District. The purpose of an APT is to determine the hydrologic parameters of an aquifer. In particular, an APT is used to determine the transmissivity, leakance, and storage values of the aquifer. Transmissivity is a measure of how easily water flows through the ground, and storage is a measure of the amount of water in the porous spaces of the aquifer. Generally, a higher transmissivity value and a lower storage value indicate better confinement. There have been three APTs conducted at the NEWF. The first APT (APT-1) was conducted in 1989 as part of the initial permitting of the NEWF. A high transmissivity value and a low storage value were calculated in APT-1. A leakance value was not calculated. The results of APT-1 were presented to the District to justify the City’s request to pump 9.0 mgd from the NEWF, which the District approved. The 1993 permit combining the NWWF and the NEWF required the City to conduct a long-term APT in order to “determine the leakance parameter between the surficial and intermediate aquifers and the leakance parameter between the intermediate and Upper Floridan aquifers.” The permit stated that if the hydrologic parameters obtained in the APT were different from those used in the model submitted in support of the initial WUP, the City would have to revise the model and, if necessary, modify the WUP to reduce withdrawals. This second APT (APT-2) was a seven-day test conducted by the City in January 2001 in accordance with a methodology approved by the District. An “exceedingly low” leakance value of 4.5 x 10-4 gallons per day per cubic foot was calculated in APT-2. The transmissivity and storage values calculated in APT- 2 were essentially the same as the values calculated in APT-1. The District expressed concerns with the results of APT-2, and in December 2001, the District advised the City that it should “proceed with caution during the planning of infrastructure (pipelines) for the [NEWF]” because the “wellfield may not be able to produce the volume of water the City has stated that would like from the wellfield, without causing adverse impacts.”10 Based upon these concerns, the District conducted an APT (APT-3) at the NEWF in April and May 2003. The parties’ experts agree that data from APT-3 is reliable, but the experts disagree in their interpretation of the data, particularly in regards to the leakance value. The City’s experts calculated a leakance value of 1.4 x 10-4 feet per day per foot, which is a low leakance value. The expert presented by the District, Dann Yobbi, calculated a higher leakance value of 3.4 x 10-3 feet per day per foot, which suggests relatively “leaky” aquifer. The leakance value calculated by the City’s experts is more persuasive than the value calculated by Mr. Yobbi because Mr. Yobbi did not “de-trend” the data from APT-3 based upon the general declines in water levels occurring at the time of APT-3. Indeed, Mr. Yobbi testified that he is in the process of revising his report on APT-3 to address this issue and he acknowledged that the surficial aquifer showed only a “slight response” to the pumping during APT-3. The leakance value calculated by the City’s experts in APT-3 is consistent with the leakance value calculated in APT-2. The transmissivity and storage values calculated in APT-3 are also consistent with the values calculated in APT-1 and APT-2. The reliability of the leakance values and other aquifer parameters calculated by the City’s experts for the NEWF is confirmed by water level data compiled by the City pursuant to the monitoring requirements in the existing WUP. The water level data was collected from monitoring wells at the NEWF in the surficial aquifer, the intermediate aquifer, and the UFA. The City began collecting this data in 1994 and it continues to collect and report the data to the District as required by the existing WUP. The water level monitoring data reflects that the surficial aquifer at the NEWF responds almost immediately to rain events. By contrast, the intermediate aquifer and UFA show a more subdued response to rainfall events, which is indicative of good confinement, especially between the UFA and the surficial aquifer. The water level monitoring data shows that rainfall or lack of rainfall is the major controlling factor relative to the rate of surficial aquifer recharge at the NEWF. The water level monitoring data since pumping began at the NEWF shows that the pumping at 4.0 mgd is having a minimal impact on the surficial aquifer at the NEWF. Indeed, the more persuasive evidence establishes that the general decline in water levels that has been observed in the monitoring wells at the NEWF over the past several years is more likely than not attributable to the severe drought in the area and the onsite drainage features, and not the pumping at the NEWF.11 Moreover, the more persuasive evidence shows that following the start of pumping at the NEWF in October 2005, the water levels in the surficial, intermediate, and Floridan aquifers returned to the historic patterns of up and down response to rainfall events shown throughout the thirteen-year period of record: the surficial aquifer fills quickly (as it receives the rainwater directly) and empties quickly (through a combination of surface drainage, evapotranspiration, evaporation, and leakage), while the UFA responds with more gradual rising and falling (as water enters the aquifer through recharge areas and slowly percolates into the aquifer through more confined areas). The analysis of the water level data collected during APT-3 showed a similar trend in the rates of decline in the surficial aquifer as were reflected in the hydrographic record of the monitoring well data collected by the City since 1994. The natural, post-rainfall rate of decline under non-pumping conditions was consistent with the rate of decline observed during pumping conditions in APT-3. In sum, the interpretation of the water level data by the City’s experts was more persuasive than the interpretation by the District’s experts. Modeling of Predicted Drawdowns and Impacts The City utilized two different models to predict drawdowns from the proposed pumping at the NWWF and NEWF: the USGS “Mega Model” and the District’s District-Wide Regulation Model (DWRM). The models incorporated regional data published by the USGS and the District as well as site-specific data from the NEWF, including the lithologic information collected through soil borings and the hydrologic parameters of the aquifers calculated in APT-3. The models were calibrated and de-trended to remove “background conditions” (e.g., regional water level declines) so that the models would only show the predicted effects of the pumping. Once the calibration was complete, the models were run to simulate the effect of the pumping on the groundwater flows in the area. The models produced contour maps that showed the predicted drawdowns in the surficial aquifer as a result of the pumping. The USGS Mega Model predicted that pumping the NEWF at 8.77 mgd would result in drawdowns of approximately 0.5 foot in the surficial aquifer in and around the NEWF. The DWRM model predicted a 0.18 foot drawdown in the surficial aquifer in and around the NEWF when pumping the NEWF at 4.0 mgd, and a drawdown of 0.4 foot when pumping at 8.77 mgd. The same models were used to predict the “cumulative” drawdowns by taking into account pumping by existing legal users as well as the pumping at the NWWF. The cumulative models assumed pumping of 36.8 mgd from the City’s wellfields. The USGS Mega Model predicted that cumulative drawdowns in the surficial aquifer in and around the NEWF would be an additional 0.3 feet, with 8.77 mgd of pumping at the NEWF. The DWRM model predicted that the cumulative drawdowns in the surficial aquifer in and around the NEWF would be 0.4 foot with 4.0 mgd of pumping at the NEWF, and 0.6 foot at 8.77 mgd of pumping at the NEWF. The City utilized the 1995 data set of existing legal users in its cumulative DWRM modeling because that was the data set provided by the District. The difference between the 1995 data set and the more current 2002 data set is on the order of 20 mgd, which is inconsequential in comparison to the 1.1 billion gallons per day of withdrawals included in the model that are spread over the geographic extent of the District. The predicted drawdowns in the surficial aquifers in and around the NEWF would be considerably greater if the hydrologic parameters calculated by Mr. Yobbi were used in the DWRM model. For example, the District’s modeling predicted drawdowns between 1.0 and 1.2 feet in the surficial aquifer in and around the NEWF when pumping 1.5 mgd from the NEWF, 3.5 mgd from Combee, and 28.03 mgd from the NWWF. The wetlands experts presented by the parties agreed that the level of drawdown predicted by the City at the NEWF has the potential to adversely impact the wetlands on the site. The experts also agreed that there is no bright line as to the amount of drawdown that will adversely impact the wetlands. The City’s expert, Dr. Michael Dennis, testified that drawdowns in the surficial aquifer between 0.18 foot and 0.5 foot “probably” would not affect the wetlands at all, or at least “not measurably.” He also testified that drawdowns between 0.5 foot and one foot “are the drawdowns that you need to be concerned about.” The District’s expert, John Emery, testified that a drawdown in the surficial aquifer of 0.4 foot “could” adversely affect the wetlands if no mitigation is provided, but that a drawdown of 0.2 to 0.3 foot might not.12 The WIP is expected to increase the amount of water that gets to the wetlands on the NEWF site. However, the extent to which the WIP will increase the water levels in the wetlands and offset the predicted drawdowns in the surficial aquifer is unknown at this point. Limiting pumping at the NEWF to 4.0 mgd is reasonable and prudent based upon the uncertainty regarding the effectiveness of the WIP and the experts’ testimony regarding the level of drawdowns that likely would, and would not, adversely affect the wetlands at the NEWF. In sum, the more persuasive evidence establishes that the drawdown predicted at 4.0 mgd of pumping –- 0.18 foot (individually) and 0.4 feet (cumulatively) –- is not likely to adversely impact the already significantly degraded wetlands at the NEWF, particularly if the WIP is properly implemented. Demand Projections The City did not use the full 28 mgd allocated under its existing WUP. It pumped only 21 mgd in the 12 months preceding October 2003, when the permit was scheduled to expire; it pumped only 26 mgd in 2006; and the pumping for 2007 was expected to be approximately 1 mgd lower than the pumping in 2006. The City's WUP application contained population and demand projections for different years in the future. For 2014 (the permit expiration date proposed by the District), the “functional population”13 of the service area was projected to be 183,264 and the average demand was projected to be 29.5 mgd; for 2023 (the original permit expiration date requested by the City), the projections were 203,721 people and 32.8 mgd; and for 2018 (the permit expiration date now requested by the City), the projections were 192,176 people and 30.9 mgd. The projections in the WUP application were prepared in 2003, and City's primary consultant, Charles Drake, testified that the data was “accurate” and “reliable.” However, more recent data shows that the population projections in the WUP application were slightly understated. The more recent data is contained in the “Water Services Territory Population Estimates and Projections” reports prepared by the City's utility department in March 2006 and March 2007. The reports include estimates of the functional population for prior years, and projections of the functional population for future years. The estimates reflect the “actual” population for a given year in the past, whereas the projections reflect the “expected” population for future years. The estimates and projections in these reports, like the projections in the WUP application, were prepared in accordance with the methodology contained in the BOR. The District did not take issue with the projections in the reports or the WUP application. The estimated functional population of the service area in 2003, 2004, 2005, and 2006 exceeded the population projected for those years in the WUP application. On average, the projected populations for each year understated the “actual” populations by approximately 3,500 persons.14 Likewise, the population projections for future years in the March 2007 report are higher than the population projections for the same years in the WUP application. For example, the report projects that the functional population of the service area in 2014 will be 191,208 (as compared to 183,264 in the WUP application), and that population in 2018 will be 203,247 (as compared to 192,176 in the WUP application). The City presented “revised” population projections at the final hearing in City Exhibit 140. The revised projections were based on the projections in the March 2006 report, but also included data from the “water allocation waiting list” that is part of the City’s concurrency management system that was created by the City in response to legislation passed in 2005 requiring local governments to allocate and approve requests for water for new development. The population projections in City Exhibit 140 are 234,959 in 2014; 247,390 in 2018; and 264,556 in 2023. These projections include an additional 43,471 persons related to new development in the concurrency management system, as well as the additional 2,600 to 3,000 persons projected per year in the WUP application and the March 2006 report. The City failed to establish the reasonableness of the revised population projections. Indeed, among other things, the evidence was not persuasive that the additional population attributed to the new development in the concurrency management system is not already taken into account, at least in part, in the annual population increases projected in the March 2006 report.15 The most reasonable population projections for the service area of the City's utility are those in the March 2007 report.16 The record does not contain demand projections directly related to the population projections in the March 2007 report. However, demand projections for those population projections can be inferred from the WUP application (City Exhibit 1(a)(2), at 0036) and City Exhibit 140 (at page 0015). The 2014 projected population of 191,208 in the March 2007 report roughly corresponds to the projected population for 2018 in the WUP application (192,176) for which the projected demand was 30.9 mgd; and it also roughly corresponds to the projected population for 2008 in City Exhibit 140 (193,001), for which the projected demand was 28.7. Thus, in 2014, it is reasonable to expect that demand will be between 28.7 and 30.9 mgd. The 2018 projected population of 203,247 in the March 2007 report roughly corresponds to the projected population for 2023 in the WUP application (203,721) for which the projected demand was 32.8 mgd; and it also roughly corresponds to the projected population for 2009 in City Exhibit 140 (201,983), for which the projected demand was 30.2 mgd. Thus, in 2018, it is reasonable to expect that demand will be between 30.2 and 32.8 mgd. The demand projections in the WUP for 2014 (29.5 mgd) and 2018 (30.9 mgd) fall within the range inferred for the populations in the March 2007 report. Thus, even though the population projections in the WUP application for 2014 and 2018 are understated, the demand projections for those years in the WUP are still reasonable. The demand projections in City Exhibit 140 –- 35.3 mgd in 2014 and 36.6 mgd in 2018 –- are overstated as a result of unreliable population projections upon which they are based. Other Issues Duration of Permit The 1987 permit for the NWWF had a six-year duration, as did the original 1989 permit for the NEWF. The 1993 permit had a 10-year duration, but that permit did not increase the amount of authorized withdrawals; it simply combined the authorizations for the NWWF and the NEWF into a single permit. In this case, the City is requesting a permit that expires in 2018, which was a 15-year duration at the time the application was filed, but now is a 10-year duration. The District is proposing a permit with a six-year duration, expiring in 2014. The District is authorized to approve a WUP with a duration of up to 50 years. The District’s rules provide that the duration of the permit is to be determined based upon “the degree and likelihood of potential adverse impacts to the water resource or existing users.” The District’s rules require that in order for the District to approve a permit with a duration of more than 10 years, the applicant is required to present sufficient facts to demonstrate that such a permit is “appropriate.” Section 1.9 of the BOR provides “guidelines” regarding the duration of permits. The guidelines in the BOR are not binding on the District, but the nearly identical language in Florida Administrative Code Rule 40D-2.321 is binding on the District. The BOR provides that a six-year permit is to be issued for renewal permits “with modification to increase the quantity withdrawn by more than or equal to 100,000 gpd or 10% or more of the existing permitted quantities, whichever is greater.” The BOR and Florida Administrative Code Rule 40D- 2.321(2)(b) also provide that a six-year permit is to be issued “where the potential for significant adverse impacts are predicted.” The renewal permit that the City is seeking requests an increase of 8.7 mgd (from 28.1 mgd to 36.8 mgd) over the existing permitted quantities, which exceeds the 10 percent threshold in Section 1.9 of the BOR. Moreover, there is a potential for significant adverse impact from the renewal permit that the City is seeking. Accordingly, a six-year permit is appropriate under the District’s rules and the guidelines in the BOR. The City failed to demonstrate why a longer permit duration is appropriate under the circumstances of this case. District staff testified at the final hearing that the permit term should be calculated from the date the permit is issued, which will be some point in 2008. Therefore, the permit should have an expiration date of 2014. Offsite Impacts The City used the modeling described above to predict the drawdown in the UFA from the proposed pumping in order to determine whether there will be any adverse impacts on existing legal users. The predicted drawdown in the UFA in the vicinity of the NEWF ranges from 1.6 feet to 2.4 feet with 4.0 mgd of pumping at the NEWF, and between 3.4 feet and 5 feet with pumping at 8.77 mgd. The predicted drawdown in the UFA in the vicinity of the NWWF ranges from 10.0 to 14.0 feet, with 28.03 mgd of pumping at the NWWF.17 These predicted drawdowns are not expected to have any adverse impacts on existing legal users that have wells in the UFA. Most permitted wells in the UFA use vertical turbine pumps, which can easily accommodate fluctuations in water levels of five feet or more. The City has not received any complaints from existing users since it began pumping 4.0 mgd at the NEWF in October 2005. The pumping at the NWWF, which has been ongoing for more than 20 years, has not caused any adverse impacts to existing legal users. The City is required under the existing WUP to respond to any adverse impact complaints from existing legal users, and it is required to implement mitigation, as needed. In short, City is required to do whatever is necessary (e.g., relocating or increasing capacity of pump, lowering pipes) to return any well impacted by the pumping to its prior function. The City did not evaluate the potential impacts of its proposed pumping on unpermitted wells because the District does not maintain a database of unpermitted wells. However, the City acknowledges that if its pumping impacts an unpermitted well, it will be obligated to mitigate those impacts in the same manner that it is required to mitigate impacts to existing permitted users. The predicted drawdowns for water bodies in the vicinity of the NWWF and the NEWF that have designated Minimum Flows and Levels (MFLs) -- Lake Bonny, Lake Bonnett, and the Cone Ranch wetlands -- are minimal, on the order of 0.1 foot. The City evaluated the impacts of pumping on contaminated sites listed by the Department of Environmental Protection (DEP) in the vicinity of the NWWF and NEWF. Based upon the results of the modeling conducted by the City, there is no reason to expect that pumping at the NWWF and/or NEWF will have any measurable impact on those sites or lead to pollution of the aquifer. Potential Impacts of NWWF Pumping The only concern expressed by the District with respect to the pumping at the NWWF relates to the potential environmental impacts of the pumping on Lake Bonny and Lake Bonnett. The City agreed to include those lakes in its EMMP. Combee Combee is located approximately four miles south of the NEWF. There is a relatively thick clay confining unit at Combee, which, according to the District, makes it a better location for water withdrawals than the NEWF. The District conducted an APT at Combee in 2006. The hydrologic parameters derived from the APT, and the “preliminary modeling” performed by the District show that the City may be able to withdraw at least 3.0 mgd from wells at Combee. The proposed permit authorized pumping of 3.5 mgd from Combee. The proposed permit also included a phasing schedule pursuant to which pumping at Combee would be decreased to 3.0 mgd if pumping at the NEWF reached 4.0 mgd. The City expressed an interest in obtaining water from Combee throughout the permitting process. However, the City represented at the outset of the final hearing that the Combee well is “off the table because the City wishes to maximize the withdrawal allocation from [the NEWF].” The City stated in its PRO that it is “willing to consider permitting a production well at [Combee] as a potential mitigation resource, should unexpected adverse impacts require the City to divert production to a back-up resource.” The District stated in its PRO that the Combee well is “available for mitigation purposes," and that the City “should be encouraged to apply for a WUP for withdrawals from Combee up to 3.0 mgd to provide additional mitigation for pumping from the [NEWF].” Pump rotation Rotation of pumping between the wells in a wellfield is a standard practice, and it can be an effective mitigation technique. The City utilizes well rotation programs at the NWWF and the NEWF in order to minimize the stress on the production aquifers. Rotating pumping between the production wells at the NEWF is particularly appropriate because several of the wells are located in very close proximity to wetlands. Rotating the pumping will help to minimize the potential for adverse impacts to the wetlands. The actual rotation schedule is an operational decision that is made based upon observed conditions at the wellfield site, rather than something that is typically included in the WUP. Conservation and Reuse The City has a four-tiered conservation rate structure, modeled after the District’s graduated water-rates prototype. The rate structure imposes higher unit costs as individual consumption increases, thereby discouraging wasteful uses of water. The City has a comprehensive leak detection program aimed at preventing the loss of water within the City’s water distribution system. This program has helped to reduce the per- capita per-day consumption rate for the City by reducing the volume of water that is wasted before it is delivered to the consumer. The City has implemented irrigation restrictions aimed at reducing the quantities of water used by domestic customers for lawn and garden watering. The per capita rate of water consumption is a measure of the effectiveness of a water conservation program; the lower the figure, the better. The City’s per capita rate has increased in recent years, but its adjusted gross per capita rate has decreased. The adjusted gross per capita rate takes into account “significant users,” which are defined as non-residential customers other than golf courses that use more than 25,000 gallons per day or that represent more than five percent of the utility’s annual water use.18 The City’s per capita rate in 2005 was 145.69 gallons per day, and its adjusted gross per capita rate in that year was 132.01 gallons per day. The adjusted gross per capita rate may not exceed 150 gallons per day within the SWUCA. Thus, the City will be required to continue its conservation programs (and implement additional programs, if necessary) to ensure that its adjusted gross per capita rate does not exceed 150 gallons per day over the life of the permit. A portion of the City’s treated wastewater is reused for cooling at the City’s McIntosh Power Plant pursuant to a permit from DEP under Chapter 403, Florida Statutes. The DEP permit, No. FL0039772 (Major), states in pertinent part: Industrial Reuse: Effluent is reused . . . as a non-contact cooling water at the City of Lakeland McIntosh Power Generating Plant. The volume of water used on a daily basis fluctuates on an as needed basis. There are no restrictions on the volume that can be routed to the reuse system. The power plant evaporates water in the cooling process or returns cooling water into the Glendale WWTP for final treatment in the manmade wetlands treatment system. The reuse in the power plant is not required as effluent disposal. . . . . The remainder of the City’s treated wastewater is “blended” with the water used at the power plant in order to meet the conductivity standards in the DEP permit and the conditions of certification for the power plant and/or directly discharged into an artificial wetland system that ultimately discharges to the Alafia River. Section 3.1 of the BOR (at page B3-2) provides that “Water Use Permittees within the SWUCA who generate treated domestic wastewater are encouraged to demonstrate that . . . 50% of the total annual effluent flows is beneficially reused.” (Emphasis supplied). The BOR lists a number of uses of treated wastewater that are considered to be beneficial reuse. The list includes “industrial uses for cooling water, process water and wash waters” and “environmental enhancement, including discharges to surface water to replace withdrawals.” The City’s use of treated wastewater for cooling at the McIntosh Power Plant is a beneficial reuse under the BOR. The treated wastewater directly discharged by the City into the artificial wetland system is not a beneficial reuse under the BOR because it is not replacing surface water withdrawals. The BOR requires all users within the SWUCA to investigate the feasibility of reuse, and requires the implementation of reuse “where economically, environmentally and technically feasible.” The City has not recently undertaken a study or otherwise evaluated the feasibility of increasing its reuse. The draft permit attached to the District's PRO includes a specific condition requiring the City to "provide a comprehensive study of reuse opportunities encompassing the [City's] water, wastewater, and electrical utilities systems" by January 1, 2009.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the District issue WUP No. 2004912.006 with the terms and conditions contained in the draft permit attached to the District’s PRO, except that: The 2014 population referenced in the permit shall be 191,208; The adjusted gross per capita rate shall not exceed 150 gallons per day; Special Condition No. 2 shall be amended to authorize withdrawals from the NEWF at 4.0 mgd annual average and 4.8 mgd peak month, and the quantities listed in the Withdrawal Point Table for the NEWF wells shall be adjusted accordingly; Special Condition No. 4 shall be replaced with a reference to the EMMP and the conceptual WIP attached to the City’s PRO, and the list of monitoring stations in the EMMP shall be amended to include Lake Bonny and Lake Bonnet; and An additional specific condition shall be added encouraging the City to pursue a WUP for the Combee site for future water needs and/or for additional mitigation of the impacts of pumping at the NEWF.

Findings Of Fact Upon a consideration of the oral and documentary evidence adduced at the hearing in this cause, the following pertinent facts are found: 1/ By application number 25793, the applicant seeks a permit to construct and operate a proposed surface water management system to serve a 2,541 acre project within the St. Johns River Basin in Indian River County. The proposed system will consist of a perimeter dike, a central canal with interior laterals and four discharge pumps. The applicant will be discharging into the St. Johns Marsh and seeks a discharge capacity of 139,000 GPM. Three of the discharge pumps are to be located at the southeast corner of the property and a two-way 25,000 GPM pump is to be located at the intersection of the central canal and the western boundary of the property. By application number 25794, the applicant seeks a permit for the use of surface and artesian water for the irrigation of the same 2,541 acres of pasture and truck crops. The applicant requests to withdraw surface water from the St. Johns Marsh by means of a two-way 25,000 GPM pump located at the intersection of the central canal and the western property boundary and to withdraw water from the Floridan aquifer by means of eight eight-inch artesian wells. The amount requested is 5,294 acre-feet per year with a maximum monthly pumpage of 1.47 billion gallons. A staff report of the Central and Southern Florida Flood Control District (FCD) concluded that the major problem with the permit applications is the impact on water quality of the receiving bodies of water and that nutrients and other pollutants will be introduced into runoff waters discharged into the St. Johns Marsh, which is the source of the public water supply for South Brevard County. The staff therefore recommended that the applicant institute a water quality and quantity monitoring program to monitor discharges to the Marsh. The staff further recommended that the applicant not be allowed to discharge from the western property boundary nor irrigate from the ditch on the western property boundary. It was recommended that the two-way 25,000 GPM pump be installed adjacent to the other pumps located at the southeast corner of the property. More specifically, the staff found that if a permit were to be issued pursuant to application number 25793, it should be subject to the conditions that: the allowable discharge capacity to be 104,000 GPM, with discharges to be east to the St. Johns Marsh by means of one 44,000 GPM pump, one 35,000 GPM pump and one 25,000 PM two-way pump to be located at the southeast corner of the property; the applicant notify the FCD prior to any excavation of materials from land lying east of the east property boundary and, if such excavation is done, a discontinuous borrow ditch be created by either leaving 25 foot portions of undisturbed marsh or by placing 25 foot earthen plugs at approximately 500 foot intervals (this was later modified at the hearing to 1,000 foot intervals); and the applicant submit monthly reports of total daily discharges and water quality, the samples to be taken at the southeast corner of the property. With regard to application number 25794, the staff recommended that if such permit were to be issued, it be subject to the following conditions: for the use of surface water, an annual allocation of 2329.3 acre- feet per year and for the use of artesian water, an annual allocation of 2518.5 acre-feet per year, with a maximum monthly pumpage from all sources of 355.3 million gallons; no withdrawal of surface water from the St. Johns Marsh when the water level in Blue Cypress Lake drops to 22.0' msl.; surface water to be withdrawn by means of a 25,000 GPM two-way pump located at the property's southeast corner; artesian waters to be withdrawn by eight eight-inch wells with effective and operative controls placed thereon and analyses of water samples from the water discharge of each the submission of monthly reports of total monthly pumpages and total monthly flows; and permit for the withdrawal of surface and artesian water to expire on January 15, 1979. At the hearing, the applicant agreed to the recommended conditions placed upon the permits by the staff report with the exception of: the amount of the allowable discharge (staff recommending 104,000 GPM as opposed to a desired 139,000 GPM); the location of the 25,000 GPM two-way pump (staff recommending southeast corner as opposed to a proposed site on the western boundary of the property); the expiration date of January 15, 1979. The Environmental Protection Bureau of the Florida Game and Fresh Water Commission requested the FCD to delay issuance of permits for all projects in the Upper St. Johns River basin until a comprehensive water management plan for the area is formulated. Read into the record was a resolution adopted by the Commission on May 16, 1975, recommending that "the further destruction of the marsh be curtailed and a plan be formulated for the return of the diverted waters as a management tool for restoration of fish and wildlife resources." On behalf of the Florida Audubon Society, Mr. Charles Lee contended that, because of this resolution and request of the Game and Fresh Water Fish Commission and that agency's constitutional status, the FCD is precluded from issuing the subject permits. Intervenors and members of the general public who were opposed to the issuance of the instant permits expressed the following concerns: the low water quality and quantity of the St. Johns River and its marshes; the decline in hunting and fishing because of agricultural activities in the St. Johns River valley; the loss of marsh land due to agricultural activity; the lack of a basic water management program for the area; the lack of remedial measures should degradation of the water occur; and the lack of an expiration date for the surface water management system permit.
Recommendation Based upon the findings of fact and conclusions of law recited above, it is the recommendation of the hearing officer that application numbers 25793 and 25794 be granted, subject to those special conditions set forth in the Staff Report as modified by the following: In paragraph number 3 on page 14 of the Staff Report, substitute the words "1,000 foot intervals" for "500 foot intervals;" Add as paragraphs 6 on page 15, paragraph 6 on page 16 and paragraph 7 on page 18 the following: "Should the data in the monthly reports submitted by the applicant indicate the occurrence of a degradation of the waters utilized, the applicant will be required to remedy the situation causing the de- gradation." Add as paragraph 7 on page 15 the following: "7. This permit shall expire on January 15, 1979." Respectfully submitted and entered this 25th of March, 1976, in Tallahassee, Florida. DIANE D.

Findings Of Fact During approximately 1961, the Board of County Commissioners of Orange County adopted the Orange County Conservation and Water Control Act. This act included a comprehensive drainage plan. Orange County is divided into several natural drainage basins. The Petitioner is presently actively seeking to implement the comprehensive drainage plan in what is known as the Upper Howell Branch drainage basin. The proposed Lateral H-15 forms a part of the drainage plan in the Upper Howell Branch drainage basin. The proposed Lateral H-l5 would begin at the outfall of Park Lake, and would extend approximately 1900 feet to Lake Maitland. Lateral H-l5 would allow the controlled lowering of Park Lake, with excess water flowing into Lake Maitland. Lateral H-15 as proposed would be a structure with a concrete paved bottom. It would be 18 feet wide, and would have vertical side walls constructed of aluminum siding. A weir would be constructed at the Park Lake outfall, and a new crossover would be constructed at the point where Highway 17-92 crosses over the project. The depth of the structure would be 5 feet. At peak flows water would flow at four foot depths leaving a one foot free area. The structure has been designed to allow passage of peak flows of water using as little land area as possible. Vertical side walls have been proposed in order to limit the amount of property which the Petitioner would need to obtain in order to construct the project. The Petitioner's comprehensive drainage plan is designed to ultimately prevent flooding which would result from a "25 year storm". The term "25 year storm" means that there is a 4 percent chance that such a storm would occur in any given year. The Petitioner's comprehensive plan for the Upper Howell Branch basin is depicted in an aerial photograph which was received into evidence as Petitioner's Exhibit 1. Generally, waters within the basin will flow from Lake Killarney through Lateral H-22, which is nearly completed, and from Lake Bell through the Lake Bell Lateral, which has been completed, into Park Lake. The Lake Bell Lateral and Lateral H-22 permit the controlled lowering of the water in Lake Bell and Lake Killarney into Park Lake. Lateral H-15 would permit the controlled lowering of the waters of Park Lake into Lake Maitland. Waters from Lake Maitland would then flow out of the drainage basin through Howell Creek which is now extremely swampy. Petitioner proposes ultimately to clear Howell Creek so that it can accept peak water loads from Lake Maitland. The proposed Lateral H-15 would follow the channel presently followed by a naturally occurring creek bed known as the Maitland Branch. Maitland Branch is a dried up waterway during dry weather periods. When waters in Park Lake rise during rainy seasons, overflow goes through the Maitland Branch into Lake Maitland. In addition storm runoff from areas surrounding the Maitland Branch drain into Maitland Branch and then into Lake Maitland. At its most Westward point, adjacent to Park Lake, the Maitland Brunch is approximately 40- 50 feet wide. A railroad crosses the branch near to the Park Lake outfall and the pipe and culvert under the railroad control the water level in the branch. The branch then extends under Highway 17-92, and into Lake Maitland. From the railroad, into Lake Maitland, Maitland Branch is confined to a narrow channel. The Maitland Branch is not a navigable water body. Lake Maitland is a navigable water body. Petitioner's proposed dredging activities would extend approximately 55 yards into Lake Maitland in order to permit the free flow of waters through the proposed Lateral H-15 into Lake Maitland. Maitland Branch is dominated by a variety of emergent and aquatic vegetation. Maitland Branch presently serves a significant function in preserving the waters of Lake Maitland. The water quality of Lake Maitland is presently good. Tests taken within the lake do not reveal violations of the Respondent's water quality rules and regulations. The lake is, however, dominated by hydrilla, and does not support a diverse aquatic plant population. The water quality in Lake Park is inferior to that of Lake Maitland. Lake Park is dominated by algal growths. During periods of high water, the waters of Park Lake flow through Maitland Branch. The aquatic vegetation in Maitland Branch serves to filter the waters and to assimilate nutrients contained in the water before the water enters Lake Maitland. Approximately 27 acres of impervious surfaces adjacent to the Maitland Branch drain directly into the branch. Storm water runs across the surfaces into Maitland Branch generally without the benefit of any filtration mechanism at all. Without the aquatic vegetation present in Maitland Branch, this storm water runoff would enter Lake Maitland without being filtered, and without nutrients being assimilated by vegetation. Aquatic vegetation in Maitland Branch does serve the filtration and assimilative functions outlined above. The degree of filtration and assimilation that is occurring is not subject to any finite measurement. No scientific means exists for accomplishing such a measurement. The very fact that the vegetation is flourishing, provides scientific evidence that the assimilation of nutrients is occurring. Furthermore, the large amounts of toxic substances which enter the Maitland Branch would cause a very rapid and provocative deterioration of the waters of Lake Maitland unless the runoff were filtered. The fact that the water of Lake Maitland is of fairly good quality evidences the fact that filtration and assimilation functions are occurring in Maitland Brunch. The Petitioner sought to demonstrate that the aquatic, vegetation in the Maitland Branch does not serve to filter the waters, or to assimilate nutrients. Petitioner's testimony tends to show that the water quality of waters at the Park Lake outfall and at the western extremes, of the Maitland Branch are of higher quality than waters at the end of Maitland Branch closest to Lake Maitland. This evidence is not creditable. In the first place the sampling techniques used by the Petitioner's agents were inadequate. Too few samples were taken to permit the drawing of any proper scientific conclusions. The samples were not taken simultaneously and in some cases samples taken at the Park Lake outfall were taken several days prior to the taking of samples at sampling stations closer to Lake Maitland. Furthermore, samples were taken at times when vegetation in the Maitland Branch was most sparse. One group of samples was taken just subsequent to a freeze which killed all of the vegetation. Another group of samples was taken shortly after the Petitioner had removed vegetation from the Maitland Branch in accordance with a temporary permit that had been issued by the Respondent (see discussion in paragraph 9 infra) Even if the Petitioner's samples had been taken in such a way that the conclusion could be drawn that the water quality in Maitland Branch is worse close to Lake Maitland that it is at the Park Lake outfall, it would still be clear that the aquatic vegetation in the branch is performing its important environmental function. Runoff from adjacent impervious surfaces into Lake Maitland constitutes water of the poorest possible quality. It is thus to be expected that the water quality of the branch would be worse at the points farthest from the Park Lake outfall where more runoff water can accumulate. This does not however permit the conclusion that no filtration and assimilation is occurring, but rather amplifies the necessity for such functions if the water quality of Lake Maitland is to be preserved. Petitioner's proposed Lateral H-15 would constitute a source of pollution for the waters of Lake Maitland. The concrete bottom of Lateral H-15 would reduce the PH level of water the branch and could result in violations of PH standards set out in the Respondent's rules and regulations. Emergent and attached aquatic vegetation could not exist in Lateral H-15. There would be no place for such vegetation to take root. The only sort of vegetation that could take hold would be water hyacinths. During peak water flows these hyacinths would be flushed out of the branch into Lake Maitland. While water hyacinths do serve to filter water that flows through them and to assimilate nutrients from the water, they are not attached, and do not serve that function as well as attached aquatic vegetation. Since water hyacinths would be washed out of the branch during periods of heavy storm runoff, when filtration and assimilation are most essential, they would not be likely to serve to maintain the water quality of Lake Maitland to the extent that the present vegetation in Maitland Branch serves this function. Lateral H-15, with the reduced ability to preserve water quality would permit water of inferior quality from Park Lake to enter Lake Maitland, and would permit storm runoff with high levels of pollutants to enter Lake Maitland. The amount of injury to water quality in Lake Maitland that would result from replacing Maitland Branch with Lateral H-15 cannot be measured finitely. It is, however, clear from the evidence that injury is certain. The frequency of water quality violations, the degree of degradation of the water, and the amount of consequent harm to fish and wildlife in Lake Maitland that will result from Petitioner's proposed project are matters for speculation. It does appear that violations will occur, that the water will be degraded, and that fish and wildlife will be harmed. The testimony will clearly not support a finding that Petitioner has given reasonable assurance that water quality violations will not occur, that the quality of water will not be degraded, and that fish and wildlife will not be harmed. The Respondent within recent months had issued a permit allowing the Petitioner to remove aquatic vegetation from the Maitland Branch between the railroad which crosses the branch near to the Park Lake outfall , and Highway 17-92 which crosses the branch approximately halfway between Park Lake and Lake Maitland. Issuance of this permit does not demonstrate that the Respondent sees no value in the aquatic vegetation of Maitland Branch. Aquatic vegetation will rapidly reestablish itself in the area, and it will be missing for only a temporary period. In addition, the Petitioner was permitted to remove vegetation from less than half of the length of Maitland Branch.
Findings Of Fact The Respondent Harper Brothers, Inc., operates a farming and limestone mining operation in Lee County, Florida. It has filed a surface water management permit application for a project to be operated as an adjunct to the mining operation at Green Meadows Mine owned by Harper Brothers. The Respondent Harper Brothers retained consultants in the general fields of engineering, hydrology, surface water management and hydraulics to assist in the formulation of a surface water management plan for the development and operation of their mining site. As a culmination of this effort, Respondent Harper Brothers filed its application for a surface water management system, and permit therefor, with the district. The SFWMD (District), upon receiving applications for surface water management systems and related permits evaluates water quantity, quality and various environmental concerns related to water resources mandated by Chapter 373, Florida Statutes, Chapter 40E, Florida Administrative Code and Chapter 17-3, Florida Administrative Code. Such an application must meet district criteria contained in the statutes and rules in order for the surface water management permit to be issued. The district's staff makes a recommendation to its governing board for approval or denial of such permits, and often with related conditions attached. In the instant case, after review of the various water quality and environmental criteria, the recommendation of the governing board of the agency was for approval of the permit with certain conditions. THE PROJECT The project which is the subject matter of this proceeding is a rock mining operation for the mining of limestone in Lee County, Florida. The application is for the construction and operation of a surface water management system to serve a 405-acre mining operation which, in essence, involves the management of the water produced by "de-watering," or pumping-out of the active rock pit, through use of a retention area, dykes, pumps, culverts and a weir structure; with a view toward keeping the water pumped from the pit (dewatering water), and stormwaters which fall on the site, contained in a retention area which has been designed to retain all the dewatering discharge. The only water discharge envisioned off the site represents the volume of stormwater which falls thereon. The stormwater which would be discharged off the site is that water which actually falls as rain onto the retention area as well as stormwater that is pumped into the retention area from the pit through the use of the two existing dewatering pumps. During excavation of the rock pit, water is discharged from the pit into the on-site retention area through use of these two pumps. An existing weir structure allows some water from the retention area to flow through a ditch to a small lake on the Respondent Harper Brothers' property. Water from the lake is used at the rock mine and some existing farmland of Harper Brothers is supplied irrigation water from it. At present, some farmland is supplied irrigation water through a pump from the retention area and some receives irrigation from the mine pit itself through another pump. The remaining water discharged from the mine pit is held in the retention area where it infiltrates into the ground. The retention area will be surrounded by 3.5-foot high by 12-foot wide dykes. Along the south side of the retention area a double dyke system is proposed. The outer dyke will also be utilized as a road and varies from three to four feet in height with a top width of 36 feet, which will be paved. Stormwater discharged from the retention area would flow through an outfall structure located at a crest elevation of 26.75 feet, National Geodetic Vertical Datum (NGVD). The controlled elevation in the retention area is 26.3 feet NGVD which is maintained by a 3.83-foot wide "bleeder notch." Discharge from this structure would then be routed westward between double dykes under the Harper Brothers' "north-south road" down a swale on the north side of its entrance road to "no-name" slough, the ultimate "receiving waters." It was established by expert witness Missimer, for Respondent Harper Brothers, that the dewatering discharge which would be held in the retention area will infiltrate into the ground at a rate of approximately 43,000 gallons per day per acre per a one-foot elevation in water level. The rate of infiltration in the ground is directly proportional to the "head" increase so that for a two-foot water level with the resulting increased pressure or "head," the infiltration rate would be 86,000 gallons per day per acre. Based on the presently permitted maximum monthly withdrawal rate, at a point of equilibrium would be reached at a water depth in the retention area of 1.3 feet, whereby the rate of water pumped into the retention area equals the rate of infiltration into the ground without considering additionally any evaporation into the atmosphere. Thus, the bleeder notch would be set at the above elevation so that all dewatering discharges from the mine (which may contain rock and other sediments) are effectively retained on site. PRE-DEVELOPMENT VS. POST-DEVELOPMENT DISCHARGES The SF design criteria contained in Chapter 40E, Florida Administrative Code, the applicability of which is not in dispute in this proceeding, provides that the volume of stormwater discharged from such a project cannot exceed the volume of such discharges from the same surface area in its pre-development condition. The development referred to in this instance is, of course, the development of the mine and the related retention area and other water management installations or "improvements." Expert witnesses Glaubitz and Serra testifying for the Respondent Harper Brothers and SFWMD established that the quantity of pre-development discharge from the subject site or surface area, was calculated based upon a "design storm event." This means that the pre-development discharge from the Harper Brothers' mine site was calculated, based upon reviews of the watershed boundary, the slope, the vegetation types, and the hydrologic length of the watershed in the geographical area, as well as through the use of aerial photography and U.S. Geological Survey maps, to show the amounts of surface and stormwaters discharged from this site, or its pre-development surface area, during a 25-year, 3-day duration storm event, meaning a storm lasting for a duration of three days of rain of a severity that has been experienced, according to meteorological records, an average of once in 25 years in the subject geographical area. Based upon these calculations of pre-development discharge rate or volume during a 25-year, 3-day storm event, the pre- development discharge from the Harper Brothers' mine site was calculated to be a volume of 10 cubic feet of water per second (cfs). "Post-development discharge" is the rate of discharge taking into account the same 25-year, 3-day storm event, which is allowed to discharge off the project site after development is completed. The calculation of post- development discharge was computed by taking into account such factors as soil storage capability, stage discharge and calculation of the amount of retention or detention of storm water required on the site. Thus, the calculated post- development discharge of stormwater from the site as it is proposed to be designed, is nine cubic feet per second during such a 25-year, 3-day severe storm, which capability is designed into the proposed project. Thus, the post- development discharge of stormwater off the project site does not exceed, and in fact is less than, the pre-development discharge of stormwater from the site. Included within the calculations by these two experts, concerning post-development volume of stormwater to be discharged, is an analysis of the quantity of water to be retained in the retention area of the proposed project. The discharge from the retention area is controlled by the above-mentioned weir and bleeder notch. The retention area proposed by the applicant is to be used both for discharge of dewatering water from the mine pit (under the previously issued industrial water permit) as well as for retention of stormwater. This weir and bleeder notch is designed to be at an elevation which only allows discharge of a volume of water representing the volume of stormwater entering the retention area over a given period of time, and not the dewatering water from the site, which may contain rock, dust in suspension, and other sediments. The previous permit granted to the applicant, as well as the permit sought in this proceeding, would require (as all parties agree) that the dewatering volume of water, representing the water pumped from the mine pit, will totally remain on the site. The project as designed is reasonably assured to be capable of retaining all such dewatering mine pit water on-site. One critical factor considered in determining the design and site for the retention area (155 acres) and in setting the bleeder notch elevation for discharge of stormwater volume, is the infiltration rate from the retention area into the ground beneath it. The Respondent Harper Brothers established (through these uncontradicted expert witnesses) that the infiltration rate is 43,000 gallons per day per acre of the retention area for a one-foot elevation of water in that retention area. One of the factors computed into the infiltration rate calculation is the "transmissivity rate." The transmissivity rate is 200,000 gallons per day per foot in the shallow or surface aquifer at the project site. Petitioner's expert, Mr. Bruns, conceded that if that rate is correct, as it was established to be, that the post-development volume of discharge leaving the project site would not exceed the pre-development volume of discharge, if the maximum pumpage rate into the retention area from the pit did not exceed 8.5 million gallons per day, and it is so found. Parenthetically, it should be noted that the Petitioner presented no testimony of its own concerning infiltration rates or transmissivity rates. Neither did the Petitioner's expert Mr. Bruns make any calculations of quantity of discharge from the site in either a pre-development condition or post-development condition, nor was a water management or hydrologic study of the drainage basin (approximately 6 square miles) made by Petitioner's expert witness, to assist in analyzing quantity of discharge. Under certain hypothetical conditions it would be possible for dewatering discharge water from the mine, as a volume of water, to be discharged, commingled with stormwater discharge, from the retention area. Thomas Missimer, testifying as an expert witness in the fields of hydrology and water quality for Harper Brothers, was uncontradicted. His studies and calculatiops in evidence established that, with regard to the infiltration rate downward into the soil under the retention area, and the amount of water pumped into the retention area, that equilibrium is reached when pumping into the retention area reaches 8.5 million gallons per day. That is, approximately 8.5 million gallons per day infiltrate downward into the soil and thus leave the retention area and thus an 8.5 million gallon pumpage rate per day would result in a static water level in the retention area, aside from evaporation. If the Respondent pumped in excess of this figure, which might be possible under its present mine dewatering industrial use permit, then the pumpage figure might exceed the equilibrium figure and cause the volume of water discharged off the site to exceed that volume which only represents stormwater. Accordingly, the parties stipulated that the maximum daily pumpage rate of 8.5 million gallons per day would be included as a condition in the permit, if it were issued to the Respondent, such that, based upon the uncontradicted infiltration data, that the limitation to a maximum pumpage rate into the retention area of 8.5 million gallons per day from the mine pit, would be permissible. In view of this stipulation, Petitioner withdrew its contention that the post-development volume of discharge water leaving the site would exceed the pre-development volume of discharge. It was thus shown that at the maximum pumpage rate of 8.5 million gallons per day no mine dewatering discharge (as a volume of water) will leave the retention area. NON-ALTERATION OF HISTORICAL DRAINAGE PATTERNS The Petitioners also contend that the supposed alteration of historical drainage patterns by this development at the site will cause additional flooding to the Petitioner's access road to their property (residence and nursery) by the road known as Mallard Lane. In that connection, the historic pattern of stormwater discharge off the project site or its geographical area, is figured into the analysis of pre-development water volume discharge versus post-development discharge. This project, like others of its type, is mandated by the rules at issue to not alter the pre-development patterns of water discharge off the site area so as to adversely affect the property and landowners off the site. Although the pre-development discharge is generally observed and calculated by looking at a site before the development involved in a permit application takes place, in the instant case, Harper Brothers, Inc., by the authority of its previously issued dewatering and industrial water use permit had already initiated its mining operation and so pre-development conditions as they relate to this permit were not directly, physically observable. Accordingly, a hydrologic study of the drainage basin in which this project is located was performed, and, in conjunction with the use of aerial photography and U.S.G.S. quadrangle maps, the perimeter of the basin was determined and an analysis of the historical pattern of flow in the drainage basin was done. The general flow of water in the drainage basin historically is from northeast to southwest, with an ultimate discharge into the "no-name" slough, a "cypress head" or slough which generally flows in a westerly and southwesterly direction from the area immediately adjacent to the project site. Internally within this drainage basin, some old pre-development north/south dykes have blocked some of the westerly flow which historically existed at the site, thereby causing some of the water to flow in a northwesterly direction until it reaches the northern end of the north/south dykes, thence returning to the generally southwesterly drainage pattern, ultimately ending up in the slough system. A small area of farm fields was located north of the east/west access road to the site, and southerly of an existing east/west line of farm dykes, and may have drained in a southerly direction before development. There is currently no information and no evidence of record concerning how this farm field area was drained. The drainage from this area now, however, is insignificant and is calculated at approximately one cubic foot per second as a maximum rate. As the calculated post-development discharge from this project site is approximately 9 cubic feet per second, even if it be assumed that the drainage from the old farm field should be added to the post-development discharge rate from the project site itself, such an addition would only equal and not exceed the historic, pre-development discharge rate of ten cubic feet per second. The flows in a southerly direction are currently blocked by the east/west access road to the Harper Brothers' site, used by Harper Brothers. In a predevelopment condition however, the same situation existed since the southerly flow was similarly blocked by farm dykes which existed in the pre- development condition. The proposed facility is designed to have stormwater which falls on the entire project site to be pumped into the retention area. The volume of stormwater permitted to be discharged will discharge from the retention area via the above-mentioned outfall structure and will be routed westward through the double-dyke system down a drainage swale on the north side of the entrance road, and ultimately into the no-name slough. Thus, the historic drainage pattern of the basin from the northeast to the southwest will not be significantly altered by the project as designed and proposed. The project generally preserves this historic drainage pattern by discharging the drainage within the basin into the "no-name" slough as occurred in the pre-development condition which, when the above-described pre-development and post-development discharge rates are compared reveals that there will be no adverse alteration in terms of either a dearth of or excess of water supply to this natural slough system. The Petitioner's access road, North Mallard Lane, running from north to south, accessing Petitioner's property west of the project site, is indeed subject to inundation, but was subject to such inundation in the pre-development condition of the project site. This is because the slough crosses this access road. Since the post-development condition does not alter the historic patterns of drainage to any significant degree, and does not represent an alteration in the volume of discharge from the project site area over that in the historic, pre-development condition, no additional flooding to the Petitioner's access road will be caused as a result of the project installation and operation. The flooding being caused to the Petitioner's access road, indeed was shown to be related in part to culverts of insufficient size installed by Lee County, so that water tends to stand on the road surface as opposed to draining under and away from it. NON-ALTERATION OF THE pH OF RECEIVING WATERS It is undisputed that the subject project, like all such projects, under the permitting authority of SFWMD, must meet state water quality criteria contained in Chapter 17-3, Florida Administrative Code. The design of such a surface water management system must include "best management practices" (BMP's) in order to satisfy the district's design criteria. BMP's are techniques which are incorporated into the design of such a system to enhance water quality such as the use of swales, retention ponds, and gravity structures. Given that the project will utilize a retention area, grassed swales and other well accepted water management structures, the design was shown to comport with "best management practices." Water quality measurements for the only water quality parameter in dispute, that of pH, were taken on the project site using standard, accepted scientific methods and U.S. Geological Survey Water Quality Standard sampling techniques. The tests revealed a pH in the retention area itself of 7.91 pH units. The pH in the pit area was 7.8 pH units and in the off-site water in the slough, the pH was 7.3 units. The water discharge from the retention area would be a combination of stormwater (rain water) which is approximately 6 pH units in the geographical area involved, and the retention area water at approximately 7.8 pH units. The precise pH of this discharge water would depend on the quantities of water from each source, but was shown to be almost neutral or approximately at a pH of 7. Thus, the discharge from the retention area of the commingled dewatering and stormwater, if such occurs, will not alter the receiving waters one full pH unit. Upon issuance of the permit, the applicant will still have to comply on a continuing basis with the water quality parameters of Chapter 17-3, Florida Administrative Code, and the staff of SFWMD will continue water quality monitoring after the permit is issued. There has thus been no showing that commingling of dewatering water and stormwater in the retention area and the discharge of such commingled waters to the receiving waters of "no-name" slough would affect the pH of that receiving water in a manner to exceed existing, permissible pH parameters and adversely affect water quality. Expert witness Serra testifying for the district as well as for Harper Brothers, has studied similar mining operations. Such operations, utilizing similar water management procedures, have not caused any water quality violations related to discharges of commingled dewatering and stormwater, including no violations of the pH parameters. Finally, near the conclusion of the proceeding, Petitioner, in effect, abandoned its dispute regarding the issue of compliance with the pH water quality parameter.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the candor and demeanor of the witnesses, the evidence of record and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That a Final Order be entered by the South Florida Water Management District authorizing issuance of a surface water management permit to the applicant herein for the proposed surface water management system, imposing upon the applicants the limiting and special conditions enumerated in the district staff report depicted in Exhibit 2 and incorporated by reference herein, and additionally, those two special conditions set forth immediately above.

The Issue The issue in this case is whether the Southwest Florida Water Management District (District) should issue to Century Realty Funds, Inc. (Century) Environmental Resource Permit (ERP) No. 44000227.002 (the ERP), which would modify Management and Storage of Surface Waters (MSSW) Permit No. 400227.000 (the Permit) and Stormwater Exemption No. EO1481, issued by the District to Century in July 1985 for construction of a surface water management system for Angler's Green Mobile Home Park located in Mulberry, Polk County, Florida.
Findings Of Fact The District issued Management and Storage of Surface Waters (MSSW) Permit No. 400227.000 and Stormwater Exemption No. EO1481 to Century in July 1985 for construction of a surface water management system for Angler's Green Mobile Home Park (MHP) located in Mulberry, Polk County, Florida. Angler’s Green MHP Angler’s Green MHP is an 83-acre residential golf course development of approximately 385 homes located off of State Road 37 near Mulberry. Residents at Angler’s Green own their own mobile homes and lease the residential lots pursuant to annual leases expiring December 31 of each year, with guaranteed renewal conditioned upon owner compliance with the terms and conditions of the lease. Prior to being developed as a mobile home park, the property which is now Angler’s Green MHP was part of a phosphate mining operation and was reclaimed under a phosphate mining land reclamation plan approved by the Florida Department of Natural Resources and a reclamation contract dated September 4, 1984. Final contours of the Angler’s Green site were made in accordance with the approved reclamation plan. After reclamation contouring, a 23-acre manmade (former phosphate mine pit) lake remained in the northeast quadrant of the Angler's Green site. The resulting lake had a finger arm (bay or cove) extending from the southwest corner of the main body of the lake, oriented in a north-to-south direction and located west of a peninsula of land extending into the northwest part of the lake from the north. The lake also had a short, narrow canal leading into the main body of the lake from the south; the canal connected at a right angle to longer narrow waterway to the south of and extending parallel to the main body of the lake in an east-to-west orientation. There also were two smaller ponds on the property after reclamation contouring. After reclamation, surface water onsite generally flowed westerly and discharged from the property to a railroad ditch along the western boundary of the property. The recorded post-reclamation, pre-development water level for the 23-acre lake, as indicated on the site grading plans, was around 127.1 to 127.8 feet above Mean Sea Level (M.S.L.). The 1985 Permits On July 10, 1985, the District issued MSSW Permit No. 400227.000 and Stormwater Exemption No. EO1481 to Century to authorize the construction of a surface water management system for Angler’s Green. The MSSW Permit had an expiration date of July 10, 1988. As designed, the permitted Angler’s Green surface water management system was to route internal stormwater runoff to swales, detention ponds, and catchment areas before discharging through a sidebank sand filtration system (a berm approximately 300 feet long containing an 8” perforated drain pipe covered by a filter fabric and sand filter material) to receiving waters at the northwest corner of the property. The permitted system was designed with five drainage areas known as Basins A through E. Basin A was in the southeast quadrant of the site; Basin B was to its east in the southeast quadrant of the site; Basin E was to the north of Basin A and included the 23-acre former phosphate mining pit reclaimed as an artificial lake, which was referred to as “Lake E” or sometimes “Pond E"; Basin C was to the west of Basin E; and Basin D was to the west of Basin C and to the north of Basin B. The two smaller ponds on the property were designated Pond C-1 and Pond B-1 and were located in Basin C and Basin B, respectively. Basin D was in the northwest corner of the site; the discharge structure was in the northwest corner of Basin D. As the system was designed, stormwater from Basin E would appear to sheet flow naturally into Lake E; stormwater from Basin A would appear to flow naturally to the southwest, away from Lake E, but the system routed the water from the southwest corner of Basin A to the western end of the waterway on Lake E through an underground pipe. Stormwater from Basin B was to flow to and be retained in Pond B-1; as the system was designed, surface water was not designed to discharge offsite from Basin B. As designed, Lake E served as a detention pond for water from Basin E and Basin A. It was to have a control structure (CS-1) in the arm of Lake E that would produce a seasonal fluctuation range of two feet, from 127.5’ above M.S.L. to 129.5’ above M.S.L. Stormwater discharging from CS- 1 was to be conveyed by pipe to Pond C-1, where it was to mingle with surface water draining from Basin C. When full, Pond C-1 would cascade into the golf course area in Basin D and, as necessary, in a portion of Basin B. After catchment and detention in the golf course area, overflow was eventually and ultimately to discharge offsite through the side-bank sand filtration system in the northwest corner of Basin D. In this manner, the Angler’s Green surface water management system was designed to accommodate the 24-hour, 25- year storm event, which was estimated to produce approximately 8 inches of water in a 24-hour period. It also was designed to comply with the water quality requirements as specified in Florida Administrative Code Chapter 17-25 (1985 Ann. Supp.) by detaining the first half-inch of runoff before discharging it offsite through the sidebank sand filtration system in the northwest corner of Basin D. (All rule citations are to the Florida Administrative Code.) Omission of the Stangls During the review process, the District noted from drawings submitted as part of Century's MSSW Permit application that the project area did not include approximately the eastern third of the main body of Lake E. District staff brought this to Century's attention in a request for additional information (RAI) and stated: "If possible, you should obtain a perpetual right to operate and maintain the lake from other owners." In response, Century falsely represented to the District that L. Kirk McKay, a joint venture partner of Century, was the only riparian owner on Lake E and that Century had obtained from him a perpetual right to operate and maintain Lake E as part of the MSSW Permit. In fact, the Stangls owned property on the east side of the lake, including approximately 500 feet of lakefront and contiguous lake bottom. The Stangls and two partners purchased the property from McKay himself in 1979. The Stangls bought out their partners in 1984. The District relied on Century's misrepresentation. The District would not have issued the MSSW Permit to Century if the District had known that Century did not own or control all the land being used for the Permit--specifically, including all of Lake E. See Rule 40D-4.101(1)(d) and (2)(d)6. (1985) (application must include "evidence of ownership or control"). In addition, because the District was unaware of the Stangls' ownership of a portion of Lake E, the District did not require Century to give the Stangls direct, actual notice of the Century's permit application. Instead, the District only required that Century publish notice of the District’s receipt of the permit application. Notice was published on April 3, 1985, in the Lakeland Ledger, a newspaper of general circulation qualified under the terms of Section 50.011, Florida Statutes. But the Stangls did not see the published notice, were unaware of the permit application, and did not ask to participate in the permitting process. The Stangl property adjacent to Angler’s Green remained undeveloped and unoccupied until 1999, when the Stangls' son, John, established a business on the site. Prior to 1999, the Stangls visited the property a couple times a year. They were fully aware of the construction and operation of Anglers Green as a mobile home park across Lake E. During this time, Century leased 385 lots with guaranteed annual renewal conditioned only upon compliance with lease terms and conditions. Amenities under the leases included clubhouse and golf course privileges. At no time before 2000 did the Stangls take any action to challenge the validity of Century's 1985 MSSW Permit. 1985 Surface Water Management Permitting Requirements In 1985, permitting requirements for surface water management systems were divided between two regulatory schemes. Surface water management permits in Polk County were issued by the District under Chapter 373, Florida Statutes, and Rule Chapters 40D-4 and 40D-40, which addressed water quantity and flooding issues for projects greater than and less than 40 acres, respectively. Water quality permits or exemptions from water quality permitting requirements were issued by the Department of Environmental Regulation under Chapter 403, Florida Statutes, and Rule Chapter 17-25 to address water quality concerns. It was not until 1988 that permitting requirements were consolidated into the MSSW regulatory program administered by the District under Rule Chapters 40D-4 and 40D-40. In 1985, the District did not have a Basis of Review (BOR) to specify system design requirements for applicants to provide reasonable assurances that the conditions for issuance of surface water permits were satisfied. Standards and criteria for the design and performance of surface water management systems were contained in Rule 40D-4.301(2) (1985) Under subsection (2)(i) of that rule, projects designed to meet the requirements of Chapter 17-25 [Regulation of Stormwater Discharge] were presumed to meet applicable State water quality requirements. There were no requirements for wet detention pond littoral zones. 20. Under Rule 17-25.03(2)(b) (1985 Ann. Supp.), stormwater management systems for projects with drainage areas less than 100 acres that provided retention or detention with filtration of the first half-inch of runoff were exempt from the permitting requirements of Rule Chapter 17-25. 21. In 1985, District Rule 40D-4.301(2)(j) (1985) allowed for natural areas and existing water bodies to be used for stormwater retention or detention purposes when not in conflict with environmental or public use considerations. Areas that could be considered for this purpose included previously-degraded areas or man-made areas (such as borrow pits). Apparently, the District allowed Century to use Lake E as a detention pond under this provision. Deviations from MSSW Permit Angler’s Green MHP was constructed in two phases, with the first phase completed in 1985, and the second phase completed in 1987. Construction of at least the part of the surface water management system to serve the first phase took place prior to 1985; it was not clear from the evidence whether construction of the part of the surface water management system to serve the second phase also took place prior to 1985, but it clearly took place prior to construction of the second phase in 1987. Condition No. 4 of Century's MSSW Permit required the submittal of a certification that the system was constructed in accordance with the approved and permitted design. But Century did not provide any such certification. Century also never certified to the District that its new stormwater discharge facility, as constructed, continued to qualify for exemption from State water quality requirements. Although the surface water management system was constructed and operating, the District never transferred the 1985 Permit to the operation phase. In several respects, the Angler’s Green surface water management system was not constructed as designed, approved, and permitted in 1985. The pipe to convey stormwater from the southwest corner of Basin A back to the Lake E waterway apparently never was constructed; instead, stormwater from Basin A was routed to Pond B-1. (There also was a berm constructed in Basin A near the southern boundary of the site; but that berm apparently was a visual berm, and there was no evidence that it affected performance of the surface water management system.) Control structure CS-1 (which was supposed to be located in the arm or bay of Lake E) and the pipe to convey overflow from there into Pond C-1 also never were constructed. By the early 1990's, Angler's Green was experiencing flooding in the golf course area in Basin D and B for extended periods of time. In November 1993, the District responded to a complaint of flooding in that vicinity. Upon investigation, the District determined that malfunction of the surface water management system serving Reservation Lakes (now known as Paradise Lakes), a development to the north and downstream of the Angler's Green system, was causing water to back up through the wetlands and the sand filtration system in the northwest corner of the Angler’s Green project. As a result, water overtopped the discharge structure, equalized at levels above the top of the discharge structure's berm, and flooded the golf course for extended periods of time. At some undetermined point in time, an unpermitted pond was dug in Basin D, apparently in an attempt to alleviate flooding of the golf course. In addition, possibly for the same purpose, a pump was installed in Basin D near Pond C-1, and a pipe was installed to convey stormwater from there into Lake E. The sidebank sand filtration system designed to provide filtration of stormwater prior to discharge from the northwest corner of the site does not appear to exist today. It may be present but difficult to see after 15 years of plant growth; or it may have been removed or disturbed as a result of re-grading in the area. However, the evidence proved that the discharge structure was present in 1993, and there is no reason to believe that it was not installed during construction of the surface water management system--i.e., by 1987 at the latest. In addition, at some undetermined point in time, a pipe was installed at the northeast corner of Lake E to convey overflow from Lake E eastward to a drainage ditch located alongside SR 37 to the north of the Stangls' property. No witnesses could testify as to when the pipe to the SR 37 ditch was installed or its elevation. (The District and Century state in their PRO that Map No. 2 in P/I Exhibit 14--an aerial map/survey submitted to the District by Century on August 13, 1990, as part of Century's 1990 Water Use Permit No. 209993.000 application--notes the pipe's elevation as 127.95 feet above M.S.L.; but no such finding could be made from review of the exhibit.) Roads in Angler's Green have inverted crowns to convey runoff from roads, driveways, and roofs away from mobile home lots. Some runoff from these impervious surfaces appears to be directed into a swale on the east side of the site; this swale leads to Lake E. In addition, approximately 12 drains have been installed in or near roads in Angler's Green that convey water through pipes directly into Lake E or Pond C-1. Under current Rule Chapters 40D-4 and 40D-40, road drains connecting impervious surfaces to Lake E would have to be shown on application construction drawings, and separate stormwater calculations would have to be provided in an application. But in 1985 this was not required. Century's calculations, together with flow arrows on drawings showing the direction of stormwater flow towards the detention ponds, were considered sufficient--especially since Century's calculations used a relatively high runoff co-efficient. As a result, the existence of these drains and pipes are not considered to be substantial deviations from the original, approved design. Similarly, approximately 64 roof drains and pipes conveying water from roofs directly into Lake E and Pond C-1 would not be considered substantial deviations from the original, approved design. In addition, these apparently were installed by mobile homeowners over the years, not by Century. From 1985 to 2000, the District did not have occasion to address regulatory concerns at Angler’s Green, except for the complaint of flooding in the golf course area that occurred in November 1993 and a more recent complaint about an area of the golf course that was designed to flood under certain conditions. Otto Stangl’s Complaint and the District’s Response Around November 1999, John Stangl noticed a fish kill in the ditch along SR 37 near the Stangl property. He also was contacted by a governmental compliance officer concerning the fish kill. Upon investigating, John Stangl saw the unpermitted pipe leading from Lake E that was discharging into the SR 37 ditch where the fish kill was observed, as well as the unpermitted pump that was pumping water from the Angler’s Green golf course area through a pipe that discharged into Lake E. In February 2000, Otto Stangl complained to the District about the fish kill and the existence of the unpermitted structures associated with Lake E. Upon receiving Otto Stangl’s complaint, District staff conducted site visits of the Angler’s Green project. Staff observed the unauthorized pump and pipe conveying water from Pond C-1 to Lake E and the unauthorized pipe conveying water from Lake E to the SR 37 ditch. Staff also observed that the Lake E control structure was missing, the pipe to convey stormwater from Basin A to Lake E was missing, and Basin D had been re-graded. In February 2000, the District also became aware of the fact that Century did not have full ownership or control of Lake E. On March 15, 2000, the District issued Century Notice of Non-Compliance and directed Century to either construct the system as designed and permitted or to seek a permit modification. On May 8, 2000, Century submitted a letter application to modify the original MSSW Permit No. 400227.000 by constructing the originally permitted Lake E control structure and pipe conveying water from Lake E to Pond C-1, but in a different location in Lake E than originally permitted due to the existence of homes at the location where these structures were originally planned. The application was subsequently amended to be a formal modification upon Century’s request for further modification to allow Basin A stormwater to flow to Pond B-1 and to expand Pond B-1 and add a control structure and an effluent filtration system. Despite having actual knowledge since at least February 2000 that the Angler's Green surface water management system was built partially on their property, the Stangls did not ask for a hearing on the 1985 Permit. Instead, they awaited the District's consideration of Century's modification application and sought to challenge the District's notice of intent to grant the modification permit issued on October 29, 2001. The District’s Regulatory Compliance Practices In the 1980's, the District appeared to pay little or no attention to construction of permitted projects or submission of required post-construction certifications. Many projects permitted by the District in the 1980’s, such as Angler’s Green, were built and operating although no certifications had been submitted; as a result, the permits issued for these projects never were transferred to the operation phase. Eventually, some projects not built in compliance with issued permits came to the attention of the District, typically through third-party complaints about drainage problems and flooding. By this time, there was a large backlog of issued construction permits for which no required post-construction certifications had been submitted. The backlog of these older projects was so large that the District decided not to initiate an aggressive, systematic, and comprehensive review of all permits for which no required certifications had been submitted. Instead, projects were checked on an ad hoc basis as complaints regarding the functioning of their surface water management systems were registered. When it came to the attention of the District in this manner that a project had been built under an MSSW permit but that no required certifications had been submitted, the District first attempted to secure the required certifications in the form of certified as-built construction drawings and a Statement of Completion, as required by BOR 2.7. In so doing, it was common practice for the District to accept certifications beyond the expiration date on a permit. If projects were substantially completed, the District would not deem the permit as expired simply because the required certifications had not been submitted before the expiration date; and such projects did not lose their status as being permitted. It should be noted that, according to the testimony of the District's expert, William Hartmann, this agency practice was not based on an interpretation of Rule 40D- 4.321(1)(b) (1985) (on duration of construction permits). Rather, the agency practice was to ignore the expiration of the construction permit under those circumstances. In addition, it does not appear from the evidence that the District ever before has faced the situation presented in this case--where a person on whose property part of a surface water management system was built without the person's consent opposes modification and asserts the construction permit has expired. In cases where the agency's practice was applied, if the required certified as-built construction drawings and Statement of Completion could not be provided because the project was not built in accordance with the MSSW permit, the District would require the permittee to either bring the system into compliance with the approved permit designs or obtain a modification of the construction permit. Letter modifications would be accepted when the requested modification would not substantially alter the permit authorization, increase the authorized offsite discharge, impact the environmental features of the project, decrease the required retention/detention, decrease the required flood control elevations for roads or buildings, or decrease pollution removal efficiency. See Rule 40D-4.331(2)(b) (1985). (The current version of the rule adds renewal or extension of the existing permit duration.) Alterations meeting the threshold requirements for a letter modification would be presumed to meet the conditions for issuance for a permit. Otherwise, formal permit modifications would be required. When application is made for a permit modification, the District’s practice is to evaluate those aspects of the surface water management system being modified. Review generally would not extend to the entire system. Permittees seeking to modify their surface water management systems generally are not required by the District to bring the unmodified portions of the system into compliance with current design criteria. Proposed ERP Permit Modification ERP Application No. 44000227.002 seeks authorization to modify portions of the Angler’s Green surface water management system. The specific alterations for which approval is sought are: permanent removal of the existing, unpermitted 18-inch pipe between Lake E and SR 37 roadside ditch; permanent removal of the pump and associated piping conveying water from Pond C-1 to Lake E; installation of the control structure (CS-1), together with installation of pipe to convey water from the control structure to Pond C-1, as designed and approved in the 1985 Permit but different location in the northwest corner of the main body of Lake E; re-grading of the northwesterly portion of the golf course to more closely conform to the original permitted plan and help keep Basin B separate from Basin D; reconstruction of the side-bank sand filter system in the northwest corner of the property, as designed and approved in the 1985 Permit but with a slightly higher invert elevation (122.04 feet above M.S.L.) to prevent water from backing up into Angler's Green from Paradise Lakes again, and with a concrete flume and spreader swale between Pond C-1 and the berm of the side-bank sand filter system; enlargement of Pond B-1; installation of a control structure on Pond B-1; and installation of 100 feet of 6-inch side-bank sand filter discharging to the southwest corner of the property from Pond B-1. By removing the unpermitted pipe to the roadside ditch along SR 37 and by constructing control structure CS-1, with the same control elevations as in the 1985 Permit (albeit at a different location in Lake E), and connecting CS-1 by pipe to Pond C-1 as envisioned in the 1985 Permit, the function of Lake E should approximate its function under the design approved in 1985. Modifying the permitted design to authorize Basin A to flow to Pond B-1 instead of Lake E results in less water flowing to Lake E; these changes will not increase water quantity or quality impacts to Lake E, as compared to the 1985 Permit. As compared to reclamation conditions prior to implementation of the 1985 Permit, water quantity and quality impacts to Lake E would be expected both under the system as designed and permitted in 1985 and as proposed to be modified, by virtue of the similar use of Lake E as a detention pond under either system. Pond B-1 is being enlarged to better accommodate the flow from Basin A. The control structure being added at Pond B-1 will control flow into the swale to the west so as to address water quantity impacts in that area. Stormwater calculations for the revised Pond B-1 demonstrated that the post-development discharge rate will not exceed the pre- development discharge rate, so that there are no concerns for adverse water quantity impacts to receiving waters or adjacent lands or flooding impacts to on-site or off-site property. The historical flows to the west are still maintained. The discharge structure being added at Pond B-1 will account for treatment of the Basin A flow. Based on calculations for revised Pond B-1, the enlarged pond will retain and percolate half an inch of stormwater runoff from the contributing area in 36 hours (which is consistent with current BOR design requirements). The proposed Pond B-1/Basin B modifications, including the routing of Basin A stormwater to Pond B-1, will not adversely affect the quality of receiving waters in that vicinity such that state water quality standards would be violated. Angler's Green is located in the Southern Water Use Caution Area of Polk County. No surface or groundwater levels or surface water flows have been established for this area under Section 373.042, Florida Statutes. The proposed modifications do not involve any works of the District. The proposed modifications are based on generally accepted engineering and scientific principles and employ treatment methods of effluent filtration which involve commonly accepted designs that can be effectively performed and function as proposed. There are no concerns about Century’s financial, legal, or administrative capability to undertake the proposed modifications as specified in the permit, if issued. There are no applicable special basin or geographic area criteria established for this area. Environmental Concerns As with its review of the proposed permit modification for water quantity impacts, the District's review of environmental concerns was limited to review of impacts from the proposed modifications to the original permitted design; unmodified portions of the original permit were not reviewed for compliance with current requirements. An approximately 20 square-foot permanent impact is proposed to Lake E due to the placement of the control structure (SW-1) in the water. A 379 square-foot temporary impact is proposed to Lake E due to the placement of a cofferdam to facilitate construction of the control structure. Temporary impacts to Lake E resulting from the construction of the control structure would be addressed through the use of sediment and erosion controls to prevent possible sedimentation and turbidity that may arise during the construction activity. The placement of a control structure in Lake E would create very minor permanent impacts resulting from the loss of the footprint of the control structure. These impacts would be insignificant. Due to the very minor nature of these proposed impacts, no mitigation would be required, and no loss of wetlands would be required to be recorded on the Wetlands/Surface Water Table. Construction of SW-1 would not adversely impact the value of functions provided to fish and wildlife, and listed species including aquatic and wetland dependent species, by wetlands, other surface waters and other water related resources of the District. No secondary impacts would be expected from construction of SW-1. No unacceptable cumulative impacts upon wetlands and other surface waters would be expected to occur as a result of construction of SW-1. The project area includes .71 acre of herbaceous/forested wetlands (WL-1) in the northwest corner. The potential for secondary impacts is addressed by an existing fence surrounding WL-1, which eliminates concerns for secondary impacts to this wetland area. No adverse impacts would be anticipated to occur to these wetlands, and no adverse secondary impacts to the water resources would be expected to occur as a result of the proposed modifications themselves. The proposed modifications would not cause unacceptable cumulative impacts to wetlands and other surface waters. Class II or Class III waters would not be affected by the proposed modification project. Therefore, Rule 40D- 4.302(1)(c) is not applicable. No seawalls, lagoons or estuaries are involved in this project. Therefore, Rule 40D-4.302(d) is not applicable. The proposed modifications would not be contrary to the public interest. Relocation of a control structure and enhancement of the Basin B portion of the system would create no significant change in impacts. The proposed modifications constitute a slight improvement over water quality from the original permitted design. No threatened or endangered species were identified for Angler’s Green. The proposed relocation and construction of the Lake E control structure, preservation of onsite wetlands in the northwest corner, and re-design of Pond B-1 present no environmental concerns. Consequently, the proposed modifications do not create any potential for adverse effects regarding the conservation of fish and wildlife, including endangered or threatened species or their habitats. The proposed modifications do not adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity. The project area does not involve navigable waters and does not affect the flow of water or cause harmful erosion or shoaling. Hence, Rule 40D-4.302(1)(a)(3) does not apply to this permit modification application. There are no significant historical and archaeological resources involved in this Project. Therefore, Rule 40D-4.302(1)(a)(6) is not applicable to this permit modification application. The proposed modifications would not be contrary to the public interest; they would not adversely affect the public health, safety or welfare or the property of others. No adverse impacts are anticipated to occur as a result of the proposed modifications. The proposed modifications maintain the historic water elevation for Lake E and maintain historic flows for the project area. The modified system should also provide some improvement in water quality.

The Issue The central issue in this case is whether the application for a surface water management permit (permit no. 4-009-0077AM) filed by the Respondent, David A. Smith (Applicant), should be approved.
Findings Of Fact Based upon the prehearing stipulations of the parties, the testimony of the witnesses, and the documentary evidence received at the hearing, the following findings of fact are made: The Applicant is the owner of the subject property. The Applicant filed an application for a permit to construct a stormwater management system which was proposed to serve a residential and golf course development to be known as Sabal Hammocks. The site of the proposed project is approximately 720 acres in size and is located in township 24 south, sections 28, 29, 30, 32, 33, and 34, range 35 east, Brevard County, Florida. The entire project site for the Sabal Hammocks development is located within the boundaries of the St. Johns River Water Management District. To the west of the project site is an 140 acre public park that treats its own stormwater and releases pre-treated stormwater during some storm events into the canals on the Sabal Hammocks site. The Applicant's site is located adjacent to Lake Poinsett and prior uses of the land have included cattle grazing and the cultivation of rye and oats. The Applicant filed his application for the stormwater management permit (permit NO. 4-009-0077AM) on December 22, 1989. That application was deemed complete by the District on June 19, 1990. The District issued a notice of its intended action to approve the permit application on June 28, 1990. Save timely filed a petition challenging the proposed action. By law the District is the appropriate agency charged with the responsibility of reviewing applications for stormwater management permits within the subject area. Save is an association of individual persons and representatives from groups who utilize the waters of Lake Poinsett and its surrounding areas for recreational and business purposes. The receiving waters for stormwater discharge from the proposed Sabal Hammocks development will be Lake Poinsett. That water body is classified as Class III waters. Currently, a dike system exists along the southern boundary of the subject property. That dike system separates the internal grazing lands of the parcel from the lower marsh and flooded areas external to the dike. A series of ditches cross the parcel to drain the interior areas. Two agricultural discharge pumps are currently in use at the site. The operation of those pumps has been authorized pursuant to a consent order approved by the District's governing board on December 13, 1990. The dike system on the subject site has been in place since the 1970s. The original construction specifications of the dike are unknown. Sometime in the 1980s, several openings or breaches were cut in the dike system. Those breaches were opened pursuant to permits issued by the District and the Department of Environmental Regulation (DER) . The breaches were cut to a sufficient width and depth to allow boats to navigate through to interior areas of the subject property during those times when the water levels outside the dike would allow such entrance. The breaches were not cut to ground level and the original dike remained intact and uncompromised by the breaches. That is, the dike has not failed to impede water movement and the integrity of the dike was not weakened by the breaches. The original outline, dimension of the dike, remained visible despite the breaches. In 1986, the Applicant requested permission from the District staff in order to close or restore the dike breaches. At that time, the District staff advised David Smith that a permit would not be required to restore the dike since such improvements would be considered a maintenance exemption. Subsequently, and in reliance upon the representations made by the District's director,, the Applicant closed the breaches and restored the continuity of the dike system of the subject property. The Applicant's work to close the breaches was performed in an open manner, would have been visible to persons using the adjacent marsh or water areas for recreational purposes, and was completed at least one year prior to the application being filed in this case. Neither the District nor DER has asserted that the work to complete the original dike in the 1970s, nor the breaches completed in the 1980s, nor the restoration of the breaches in 1986 was performed in violation of law. Further, the District had knowledge of the subject activities. Save contends that the restoration of the dike system was contrary to law and that it was not afforded a point of entry to contest the closure of the breaches. Additionally, Save infers that the original construction of the dike system in the early 1970s was without authorization from authorities. Save's contention is that the prior condition of the property, ie. the parcel with breached openings, must be considered the correct pre- development condition of the land. The District, however, considered the pre- development condition of the parcel to be that of a diked impoundment separated from Lake Poinsett. The same assumption was made regarding the pumping of water from the area enclosed by the dike via an existing 36 inch pump which discharges to Bass Lake (and then to Lake Poinsett) and an existing 12 inch pump that discharges into the marsh areas adjacent to the property (between it and Lake Poinsett). The District's consideration of the site and the application at issue was based upon the actual condition of the land as it existed at the time this application was filed. The pre-development peak rate and volume of discharge from the site was calculated based upon the maximum discharge capacity of the two existing pumps (described above). Accordingly, the maximum pre-development rate of discharge from the two existing pumps is in the range of 90-107 cubic feet per second. The pre-development volume of discharge, based upon actual pump records, was calculated as 710 acre-feet for a 25 year, 96 hour storm event. The total areas encompassed by the Applicant's proposal are the 720 acre site where the golf course and residential homes will be located together with 140 acres from an adjacent public park. The runoff entering the stormwater system from that public park will have already been treated in its own stormwater management system. The Applicant's proposed stormwater system will consist of a series of lakes and interconnected swales. This wet detention system will capture the runoff and direct its flow through the series of swales and lakes via culverts. The waters will move laterally from the northwestern portion of the parcel to she southeastern end of the site. From the final collecting pond, she waters will be pumped to Bass Lake and ultimately flow to Lake Poinsett. Wet detention systems generally provide greater pollutant treatment efficiencies than other types of stormwater treatment systems. The maintenance associated with these systems is also considered less intensive than other types of treatment systems. The wet detention system proposed for Sabal Hammocks accomplishes three objectives related to the flow of stormwater. The first objective, the collection of the. stormwater, requires the creation of several lakes or pools into which water is directed and accumulates. The size and dimension of the lakes will allow the volume of accumulated water to be sufficient to allow stormwater treatment. The capacity of the lakes will also provide for a sufficient volume to give adequate flood protection during rainfall events and storms. The second objective, the treatment of the stormwater, requires the creation of a littoral zone within the system. The littoral zone, an area of rooted aquatic plants within the lakes or ponds, provide for the natural removal of nutrients flowing into the system. The plants serve as a filtering system whereby some nutrients are processed. The proposed littoral zone in this project constitutes approximately 37 percent of the detention system surface area and therefore exceeds District size requirements. The depth of the treatment volume for the proposed system will not exceed 18 inches. A third objective accomplished by the creation of the series of lakes is the provision for an area where pollutants flowing into the detention system may settle and through sedimentation be removed from the water moving through the system. The average residence time estimated for runoff entering the Sabal Hammocks detention system is 48 days. The permanent pool volume will, therefore, be sufficient to assure the proposed project exceeds the District's requirements related to residence time. The design and volume of the Sabal Hammocks system will also exceed the District's requirements related to the dynamic pool volumes. In this case the Sabal Hammocks system will provide for approximately 65 acre-feet of runoff. Thus, the proposed system will adequately control and detain the first 1 inch of runoff from the site. The length to width ratio for the proposed lakes, 18:1, exceeds the District's minimum criteria (2:1). The final lake or pond into which the stormwater will flow will be 17 acres and will have 15 acres of planted wetland vegetation. Before waters will be released into Bass Lake, the site's runoff will pass through 3100 linear feet of this final lake before being discharged. The proposed project will eliminate the two agricultural pumps and replace them with one pump station. That station will contain four pumps with a total pumping capacity of 96 cubic feet per second. Under anticipated peak times, the rate of discharge from the proposed single station is estimated to be less than the calculated peak pre-development rate of discharge (90-107 c.f.s.). The estimated peak volume of discharge will also be lower than the pre-development discharge volumes for the comparable storm events. The proposed pump station is designed to be operated on electrical power but will have a backup diesel generator to serve in the event of the interruption of electrical service. Additionally, the pumps within the station will be controlled by a switching device that will activate the pump(s) only at designated times. It is unlikely that all four pumps will activate during normal rainfall events. The Applicant intends to relinquish maintenance responsibilities for the stormwater system including the pump station to Brevard County, Florida. Finished floor elevations for all residential structures to be built within the Sabal Hammocks development will be at a minimum of 18.2 mean sea level. This level is above that for a 100 year flood. The floor elevations will be at least one foot above the 100 year flood elevation even in the event of the dike or pump failure or both. Finished road elevations for the project will be set at 17.5 feet mean sea level. This elevation meets or exceeds the County's requirements regarding the construction of roadways. It is estimated that the Sabal Hammocks system will retain at least 26 percent of all storm events on site. If the lake system is utilized to irrigate the golf course the proposed system could retain 45 percent of all storm events on site. Of the 31.27 acres of wetlands within the proposed site, only 4.73 acres of wetlands will be disturbed by the construction of this project. Some of the wetlands are isolated and presently provide minimal benefits to off-site aquatic and wetland dependent species. No threatened or endangered species are currently utilizing the isolated wetlands. The areas of wetlands which are productive and which will be disturbed by the development will be replaced by new wetlands to be created adjacent to their current location at a lower elevation. The new wetlands should provide improved wetland function since those areas will be planted with a greater diversity of wetland plant species. Additionally, other wetland areas will be enhanced by the removal of invader species and increased hydroperiod in the area. The integrated pesticide management plan for the proposed project will be sufficient with the additional condition chat use of Orthene, Subdue, and Tersan LSR will be authorized when approved insecticides or fungicides have not been effective. In this case, the estimates regarding the water quality for the proposed project were based upon data from studies of multifamily residential projects. Data from single family/ golf course developments was not available. Therefore, based upon the data used, the projected runoff concentrations for this project should over estimate pollutants and are more challenging to the treatment system than what is reasonably expected to occur. In this regard, the overall treatment efficiencies are estimated to be good for all of the parameters of concern with the exception of nitrogen. The projected increase in nitrogen, however, will not adversely impact the receiving water body. The projected average concentration for each constituent which may be discharged is less than the state standard with the exceptions of cadmium and zinc. In this regard, the District's proposed conditions (set forth in the District's exhibits 4 and 9) adequately offset the potential for a violation of state water quality standards. More specifically, the use of copper-based algaecides in the stormwater management system should be prohibited; the use of galvanized metal culverts in the stormwater management system, or as driveway culverts, should be prohibited; and the use of organic fertilizers or soil amendments derived from municipal sludge on the golf course should be prohibited. Additionally, a water quality monitoring plan should be implemented by the Applicant. The monitoring plan mandates the collection of water samples from areas in order to adequately monitor the overall effectiveness of the treatment facility. The source of cadmium is not be expected to be as great as projected since the most common source for such discharge is automobiles. It is unlikely that the golf course use will generate the volume of discharge associated with automobile use that the multifamily data presumed. The projected quality of the discharges from this project should be similar to the ambient water quality in Lake Poinsett. In fact, the post- development pollutant loading rates should be better than the pre-development pollutant loading rates. The discharge from the proposed Sabal Hammocks project will not cause or contribute to a violation of state water quality standards in Lake Poinsett nor will the groundwater discharges violate applicable state groundwater quality standards. The floodways and floodplains, and the levels of flood flows or velocities of adjacent water courses will not be altered by the proposed project so as to adversely impact the off- site storage and conveyance capabilities of the water resource. The proposed project will not result in the flow of adjacent water courses to be decreased to cause adverse impacts. The proposed project will not cause hydrologically-related environmental functions to be adversely impacted The proposed project will not endanger life, health, or property. The proposed project will not adversely affect natural resources, fish and wildlife. The proposed project is consistent with the overall objectives of the District.
Recommendation Based upon the foregoing, it is RECOMMENDED: That the governing board of the St. Johns River Water Management District enter a final order approving the application for permit number 4-009-0077AM with the conditions outlined within the District's exhibits numbered 4, 8, and 9 and as previously stated in the notice of intent.

The Issue Whether the applicants own the property in question? Whether the project would comply with the criteria of the South Florida Water Management District contained in Basis of Review for Surface Water Management Systems, specifically Sections 3.1.3 and 3.2? Whether flood protection would be inadequate or septic tanks unsuitable or whether the public health and safety would be compromised or the ultimate purchasers be deprived of usage of the property due to inundation in violation of Chapter 373, Florida Statutes (1981), or Rule 40E-4.301(1), Florida Administrative Code?
Findings Of Fact Ms. Williamson and Messrs. Leggett and Collins hold in fee simple a triangular 117.24-acre parcel in Okeechobee County as tenants in common under a warranty deed executed in their favor by one W. C. Sherman. They propose to develop the property as a trailer park (complete with airstrip) large enough to accommodate 109 trailers. To this end, soil would be dug up from the center of the property and used to raise the elevation of the surrounding land above the 100-year floodplain. (T. 47) The applicants have a dredging permit from the Department of Environmental Regulation authorizing them to excavate 629,889 cubic yards. They are proposing to dig to a depth of 76 feet below ground. This would create an 18-acre body of water ("Poe's Lake") which would overflow a V-notched weir into a county canal. The county canal would take the water to C- 38, one of the large canals to which the Kissimmee River has been relegated, at a point about 18 miles upstream from Lake Okeechobee. Runoff would wash over residential lots and roadways; the site would be graded to assure drainage into Poe's Lake. The minimum road crest elevation would be 30 feet NGVD ("[a]round twenty-nine feet" T.52), as compared to the control elevation for surface waters of 28.5 feet NGVD. WATER QUALITY The developers plan septic tanks for wastewater treatment. At the close of all the evidence, counsel for the applicants stated that sanitary sewers could be installed instead. Respondents' Proposed Recommended Order, p. With all the housing units in use, at least 10,900 gallons of effluent would seep into the ground from the tanks daily. There would be some evapotranspiration, but all the chemicals dissolved in the effluent would eventually end up in the groundwater. During the dry season, septic tank effluent would cause mounding of the groundwater and some groundwater movement toward, and eventual seepage into, Poe's Lake. The eventual result would be eutrophication and the growth of algae or macrophytes on the surface of Poe's Lake. This would cause dissolved oxygen violations in Poe's Lake. Discharges from the lake would inevitably occur, aggravating the situation in C-38, which already experiences dissolved oxygen levels below 5.0 milligrams per liter in the rainy summer months. Some fraction of the nutrients in the effluent from the septic tanks would ultimately reach Lake Okeechobee itself. The sheer depth of the excavation would create another water quality problem. Under the anaerobic conditions that would obtain at the bottom of Poe's Lake, bacteria acting on naturally occurring sulfates would produce hydrogen sulfide, ammonia and various other reduced organic nitrogen compounds. These substances are toxic to human beings and would, in some indeterminate quantity, enter the groundwater from Poe's Lake. This would affect the taste and perhaps the potability of water from any well nearby. It would be "possible to design a better system where there would be nutrient removal and a greatly reduced probability of violation of the dissolved oxygen criterion and obviation of the potential for ground water contamination." (T. 200) Installation of a baffle on the weir would serve to prevent buoyant debris from entering surface waters of the state. BASIS OF REVIEW Official recognition was taken of the "Basis of Review for Surface Water Management Permit Applications Within the South Florid Water Management District," parts of which all parties agree pertain in the present proceedings. Among the criteria stated in this document are: 3.1.3 Waste and Wastewater Service - Potable water and wastewater facilities must be identified. The Applicant for a Surface Water Management Permit must provide information on how these services are to be provided. If wastewater disposal is accomplished on-site, additional information will normally be requested regarding separation of waste and storm systems. 3.2.1.4 Flood protection - Building floors shall be above the 100 year flood elevations, as determined from the most appropriate information, including Federal Flood Insurance Rate Maps. Both tidal flooding and the 100 year, 3 day storm event shall be considered in determining elevations. b. Commercial and industrial projects to be subdivided for sale are required to have installed by the permittee, as a minimum, the required water quality system for one inch of runoff detention or one half inch of runoff retention from the total developed site. State standards - Projects shall be designed so that discharges will meet State water quality standards, as set forth in Chapter 17-3, Retention/detention criteria - Retention and/or detention in the overall system, including swales, lakes, canals, greenways, etc., shall be provided for one of the three following criteria or equivalent combinations thereof . . . Wet detention volume shall be provided for the first inch of runoff from the developed project, or the total runoff from a 3-year, 1-hour rainfall event, whichever is greater. Dry detention volume shall be provided equal to 75 percent of the above amounts computed for wet detention. Retention volume shall be provided equal to 50 percent of the above amounts computed for wet detention. 3.2.4.1 Discharge structures should include gratings for safety and maintenance purposes. The use of trash collection screens is desirable. Discharge structures shall include a "baffle" system to encourage discharge from the center of the water column rather than the top or bottom. 3.2.4.4.2 b. Control elevations should be no higher than 2 feet below the minimum road centerline elevation in the area served by the control device in order to protect the road subgrade. Simply detaining runoff before discharging it offsite will not insure that the water quality standards set forth in Chapter 17-3 will be met. Whether the standards are met depends on, among other things, the composition of the runoff. FWF'S INTEREST Among the purposes of the FWF, as stated in its charter, Shall be to further advance the cause of conservation in environmental protection, to perpetuate and conserve fish and wildlife, oil, water, clean air, other resources of the State and so manage the use of all natural resources, that this generation and posterity will receive the maximum benefit from the same. (T. 248-9) Four or five thousand Floridians belong to FWF. FWF members "make use" (T. 250) of the waters of Lake Okeechobee, the Kissimmee River and specifically of the waters in C-38. PROPOSED FINDINGS CONSIDERED The applicants and FWF filed post hearing memoranda and proposed recommended orders including proposed findings of fact which have been considered in preparation of the foregoing findings of fact. They have been adopted, in substance, for the most part. To the extent they have been rejected, they have been deemed unsupported by the weight of the evidence, immaterial, cumulative or subordinate.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That SFWMD deny the pending application for surface water management permit.

Findings Of Fact In 1984, the South Florida Water Management District (SFWMD) issued surface water management permit number 48-00201-5 for a 515 acre project, Isleworth Golf and Country Club, located in southwest Orange County. The permit was issued to the developer, Isleworth Partners. Sometime after the permit was issued and the system was constructed, nitrate concentrations were detected in holding ponds BE-15 and 16. District staff speculated that the shallow ground water table was contaminated with residual nitrogen left from nutrient applications to a citrus grove previously on the site. They were concerned that the high nitrate ground water was seeping into the storm water storage ponds and would eventually be discharged into adjoining Lake Bessie, thereby affecting the water quality of the lake. Lake Bessie, along with other lakes in the region, was also experiencing rising levels. On March 24, 1988, Isleworth Partners submitted to the SFWMD its application number 03248-G, to modify the existing surface water management permit, to help prevent the water quality problems from occurring in Lake Bessie, as described above, and to ameliorate and mitigate against increased lake levels in Lake Bessie. It was not intended to provide flood protection for Lake Bessie. The solution proposed in the modification request, as well as in water use permit applications processed at the same time, was to retain substantially more water in storage ponds BE-15 and 16, and to recycle some of the water from those ponds for use in irrigating the golf course. There were no objections to the water use modifications which were processed with the surface water management permit modification, and the water use modifications were approved by the SFWMD governing board in June 1988. As they affect ponds BE-15 and 16, the water use modifications include pumping the ponds down to a new control level of 97 feet NGVD and using that water to irrigate the golf course. This process has already been implemented with beneficial results: the nitrate concentrations in the ponds have been reduced. The surface water management modification which is the subject of the application at issue is to raise the weir structure from 101.6 to 103 feet NGVD in pond BE-15 to provide complete retention of a 10 year/24 hour storm event without discharge to Lake Bessie from the pond. The under drain system at Pond BE-15 will also be plugged to prevent the existing permitted bleed down of the pond waters into Lake Bessie. This structural modification involves simple construction work and can be completed in one or two days. Ponds BE-15 and 16 are currently connected by an equalizer pipe, and will remain so. Under the modifications the ponds will be maintained (control elevation) at 97 feet NGVD through the use of existing permitted pumps. The maximum elevation of the ponds will be raised from 101.6 feet to 103 feet NGVD by the alteration of the weir. This means the waters in the ponds would have to top 103 feet to overflow and discharge, by way of an existing pipe, to the swales along Lake Bessie and thence into the lake. A 10 year/24 hour storm event is the amount of rainfall that will statistically occur in a 24-hour period once every ten years, or ten times in a 100-year period. The amount of rainfall in a 10 year/24 hour storm event is roughly seven and a half inches. The modification proposed by Isleworth Partners is intended to retain the runoff from that storm. Currently, under the system as permitted, only the first inch of runoff must be retained. This is about 2.4 inches of rainfall or approximately a 3-year/1-hour storm event. Substantially more water will be retained in Ponds BE-15 and 16 under the proposed modification. The staff of SFWMD recommended that the application be granted, with twelve standard limiting conditions and eight special conditions, including the following: * * * The permittee shall be responsible for the correction of any water quality problems that result from the construction or operation of the surface water management system. The district reserves the right to require that water quality treatment methods be incorporated into the drainage system if such measures are shown to be necessary. * * * (Isleworth Exhibit #3, p. 6) John Robertson, Donald Greer and Robert Londeree reside on Lake Bessie. John Robertson and Donald Greer are members and officers of a nonprofit corporation, the Petitioner in this case, Friends of the Lakes, Inc. These residents are concerned that the level of Lake Bessie has risen in the last few years and that it is becoming polluted. Long standing docks which had been primarily dry are now frequently under water. The residents have observed milky or greenish yellow water discharging from pipes from the Isleworth development. These residents, who are not parties to the proceeding, concede that, if the modification works as intended, the system will be improved and the impact to Lake Bessie Will be lessened. Petitioner, Friends of the Lakes, Inc., questions the reliability of the pumping system to maintain the 97.0 foot control elevation. If the ponds are maintained at a control level of 97.0 feet, the 10 year/24 hour storm water will be retained. If, however, through a series of smaller events, the level is higher than 97.0 feet, less capacity will exist, and the water will discharge sooner to Lake Bessie. The current permitted pump operates at 375 gallons a minute. Depending on whether the pump is operated continuously or part-time, it would take from four to twenty days to pump down the pond from a maximum 103 feet to the 97 foot level. The District found the pumping system to be acceptable at Isleworth because the development has a full-time maintenance staff of 35 people, of whom three work on the pumping system. A maintenance supervisor checks the pumps daily, and the developer has an agreement with a pump company to replace the pump, if needed, within four to six hours. The system is considered reliable and the increased pond holding capacity will insure that more water will be retained than under the existing permitted system. Stephen Miller is the professional engineer whose firm prepared the application for modification and the original application for the surface water management permit. He is aware of some changes in the project as constructed which differ from his design for the original system. These changes relate specifically to grading on the golf course and not, as suggested by Petitioner, to the operation of ponds BE-15 and 16. Stephen Miller believes that the modifications will do exactly what they are proposed to do. The application for the modifications took into account the existing conditions which differ from the permitted construction plans. Ronald R. Potts testified for Petitioner as an expert in geology and surface and ground water hydrology. He agrees that the application for modification meets all requirements of the SFWMD with the exception of a single standard condition: * * * 3. The permittee shall comply with all applicable local subdivision regulations and other local requirements. In addition, the permittee shall obtain all necessary federal, state, local and special district authorizations prior to the start of any construction or alteration of works authorized by this permit (Isleworth Exhibit #3, P. 6.) The district staff report recommending approval for the modification request was sent to Orange County for its review and comment. Orange County made no objections. Within Orange County it is the engineering department which is responsible for the implementation and interpretation of the Orange County subdivision regulations as they apply to storm water management. The SFWMD does not attempt to enforce other agencies' requirements. The Orange County Engineer, George Cole, determined that neither section 10.1.2 nor section 10.4.4(D) of the Orange County Subdivision Regulations were applicable to the modification proposed by Isleworth. Section 10.1.2 requires that recharge to the Floridan Aquifer, where soils are compatible, shall be accomplished by providing for retention of the total run off generated by a 25 year frequency, 24 hour duration storm event from the developed site. Section 10.4.4(D) of the Orange County Subdivision Regulations requires that a pond design detain a 100 year storm event when discharge into a lake without a positive outfall is proposed. When the County first approved Isleworth's Planned Development, it set a specific requirement that the storm water management system retain the first inch of runoff and detain the difference between pre-development and post- development discharge for a 25 year/24 hour storm. "Retention" of storm water means that the water must be held on site and disposed of by some means other than discharge. "Detention" requires only that water be held back for a period of time before discharge. The Isleworth property is not located in a prime recharge area, as under its soils is a highly impermeable lens, commonly called "hardpan." Lake Bessie has a positive outfall, a pipe connecting Lake Bessie with nearby Lake Down. Although the pipe was plugged with debris for a period of years, it has been cleaned out and the potential exists for outfall from Lake Bessie in flood conditions. The County's 100 year/24 hour detention requirement would still allow the ponds to discharge more water to Lake Bessie than the proposed 10 year/24 hour retention design, and is, therefore, less restrictive. Lake Bessie presently is one of Florida's most pristine lakes with crystal clear water that is ideal for recreational purposes. The natural dynamic state of lakes is that over a period of time they evolve from oligotrophic, with clear water and a balanced system; to mesotrophic, with less water clarity, more nutrients, increased algae and less desirability for human use; to a eutrophic state, with even less clarity, choking vegetation, less fish and less pleasing appearance and utility. This occurs in a natural state as lakes fill in with decaying matter from the shore. Petitioner claims that discharge from Isleworth will hasten the death of the lake. Phillip Sacco testified for the Petitioner as an expert biologist and limnologist (one who studies fresh bodies of water). He performed a modeling analysis to determine the amount of phosphorus being discharged into Lake Bessie and he opined that the Isleworth development will cause Lake Bessie to change to a eutrophic state. A significant component of his analysis was his assumption that 920 acre-feet of water would be discharged into Lake Bessie as a result of the modification. (transcript pp. 557-558). The 920 acre feet is actually the total amount of water which enters Lake Bessie from the entire Lake Bessie basin, not just from the Isleworth property, and includes both surface water (2%) and ground water (98%). The analysis is discredited by the false assumption. Mr. Sacco also theorized that the interaction of nitrogen and phosphorus precipitated by the change in land use occasioned by the Isleworth development would produce deleterious effects on Lake Bessie's water quality: "Nitrogen is the dynamite; phosphorus is the fuse and the land use change of Isleworth is the match." The permit modification application at issue does not relate to a land use change. The change from orange groves to residential development occurred years ago and has already been permitted. In fact, the land change providing the ignition in Mr. Sacco's vivid metaphor is just as likely in the even earlier cultivation of the groves and use of nutrients in their production. The single result of the modification at issue will be less water being discharged into Lake Bessie than is currently permitted from the system, thus conserving the water quality present in the lake. The residents who testified are not parties to this proceeding. Although two of them established they are members and officers of Friends of the Lake, Inc., no evidence was produced regarding the corporation, its legal existence or purpose.
Recommendation Based on the above it is hereby RECOMMENDED: that a final order be issued granting the application for permit modification, and denying Isleworth Partners' request for costs and attorney's fees.

Findings Of Fact The Petitioner, E. F. Guyton, has filed an application for a permit which would allow the dredging of a boat slip and construction of a sedimentation basin with boat storage, specifically requiring the excavation of a boat basin, access canal, and access channel on his property which is located on the west shore of Crescent Lake, in Putnam County, Florida. The permit application number is 54-6806. The Respondent, State of Florida, Department of Environmental Regulation, is an agency of the State of Florida which has the responsibility of appraising those applications such as the one submitted by the Petitioner, E. F. Guyton, and making a decision to grant or deny that permit. The authority for such action on the part of the Respondent resides in Chapters 253 and 403, Florida Statutes, and Rule 17, Florida Administrative Code. This cause comes on for consideration based upon the Respondent's letter of intent to deny the application, as dated August 22, 1978, after which the Petitioner has filed its petition challenging that intent to deny and requesting that the permit be granted. The petition in behalf of the Petitioner was received by the office of the Respondent on September 8, 1978. It was subsequently assigned to the Division of Administrative Hearings for consideration and that Notice of Assignment was dated September 28, 1978. The proposal for permit calls for excavation of a boat basin 100 feet wide and 480 feet long, leading into an access canal 25 feet wide and 500 feet long. This excavation is in the vicinity of an existing intermittent natural stream. The proposal would call for the removal of approximately 21,000 cubic yards of silt and sand, landward of mean high water. The excavation would be accomplished by use of a dragline to a depth of -2.0 feet MSL. The basin and canal slopes would be 2:1 and stabilization of slopes would be assured by riprap and grassing. A concrete spillway would be constructed at the upper end of the basin to direct the stream flow into the basin. In addition, the proposal calls for the dredging of an access channel through the shallow littoral zone of Crescent Lake to the mouth of the proposed access canal. The dredging involved with the access channel would cause the removal of 400 cubic yards of sediment from an area 250 feet long and as wide as 30 feet. The proposed depth of the channel is 2.0 feet MSL and slide slopes would be 5:1. The spoil would be pumped to a dike holding area on adjacent uplands. The Respondent's Exhibit No. 1, which is the permit application, offers a sketch of the boat basin with secondary sedimentation feature and the attendant access canal and channel. The project lies between U.S. Highway 17 and Crescent Lake, Areas to the south and west of the site are pasture and bayhead wetlands and they serve as a watershed for the aforementioned intermittent stream. Other upland areas in the vicinity are dominated by fully-drained flat woods and well-drained sand hill and messic oak terrain. The project site waterward of the mean high water is part of a shallow littoral zone of the west shore of Cresent Lake. The intermittent stream receives the runoff from the pastureland and drainage from U.S. Highway 17. There is a pronounced change in elevation during the course of the intermittent stream. The submerged littoral zone of the lake, which includes the proposed site of the access canal, falls away at a gentle slope and includes a number of supporting hardwoods, predominantly bald cypress. The area also includes submerged emergent vegetation, which is found in the shallows offshore. These shallows are exposed to favorable sunlight from the point of view of the health of this vegetation. The vegetation includes an emergent bed of oft stem bulrush (Sicrpus validus) which is in line with the proposed channel. Within the photic zone there is submerged tape grass (Valisneria americana) and naiad (Najas sp.). On the shore of Crescent Lake at the project site is found a hardwood swamp in its natural form, together with a creekbed which divides into numerous channels fanning out in the direction of the lake itself. This area of the creekbed contains bald cypress (Taxodium distichum), red maple (Acer rubrum), swamp ash (Fraxinus panciflora), black willow (Salix nigra), black gum (Nyssa biflra), water hickory (Carya aquatica), and wax myrtle (Myrica cerifera). The herbs and ferns in this area include penny wort (Hydrocotyl umbellata), arrow- arum (Peltandra virginica), leather fern (Acrostichum danaeifolium), and royal fern (Osmunda regalis). The sediments found in the creek area are sandy to silty sand. In the area where the boat basin/sedimentation facility would be located, the present intermittent stream is much more confined than in the area of the creekbed. Only in times of heavy rainfall does the water come outside the banks of the intermittent stream and inundate the surrounding territory. This portion of the stream is densely vegetated by a mixture of hydrophytes, facultative hydrophytes, an optimally situated upland species. These include sweet bay (Magnolia virginiana), black gum (Nyssa biflora), and red maple (Acer rubrum). Additionally, there are slash pine (Pinus elliotii), long leaf pine (Pinus palustris), dahoon (Ilex cassine), wax myrtle (Myrica cerifera), water oak (Quercus nigra), wild azalea (Ericaceae), and saw palmetto (Serenoa repens). The sedminets in this area range from very sandy in the slightly higher elevations adjacent to the stream bed to a heavy peat which is found predominantly in the bay tree locations. The uplands in the agricultural area are dominated by water oak, slash pine, long leaf pine, live oak and saw palmetto. A more graphic depiction of the project site and in particular as it relates to the intermittent stream, shore line upland agricultural area, and U.S. Highway 17 may be found in the Petitioner's Exhibits 1 and 2 and the Respondent's Exhibits 2 through 15, which are photographs of the project site. There are numerous varieties of fish in the area of Crescent Lake through which the access channel would be routed. These include: Seminole killifish (Fundulus seminolis), naked goby (Gobiosoma bosci), black bullhead (Ictalurus melas), brook silversides (Labidesthes sicculus), sunfish (Lepomis sp.), large-mouth bass (Micropterus salmoides) and Atlantic needlefish (Strongylura marina) . In addition, there are 35 species of invertebrates which were collected in the studies made by employees of the Respondent in their assessment of this permit application. The names of those invertebrates may be found in the Respondent's Exhibit No. 19 which was admitted into evidence in the course of the hearing. The vegetation and shallow water with a sandy bottom, together with the numbers and species of macro invertebrates, small fishes and immature game fishes point to the fact that this part of the lake serves as a valuable site for the propagation of fish, otherwise referred to as a spawning ground. The water quality in Crescent Lake at the site of the project is good, from the standpoint of gross observations. However, there have been some indications of eutrophication in Cresent Lake. A more complete understanding of the water quality may be gained from an examination of the Respondent's Exhibits 21 through 41 admitted into evidence. These exhibits are constituted of certain water quality reports rendered after extensive testing in Crescent Lake. The rainfall in the area exceeds 54 inches a year, with 50 percent of that rainfall being recorded in the wettest quarter, in which over 7 inches a month would fall. July has recorded 15 inches as a mean measurement over the last 80 years, with the month of May showing less than 2 inches, the month of September showing less than 2 inches and the month of October less than 1 inch. In considering the proposed project, a beginning point would be an examination of the ability of the primary filtration pond and secondary filtration function found in the boat basin, to adequately disperse the pollutants which will come into the system from the agricultural area and U.S. Highway 17. That treatment system is inadequate. The inadequacy exists because in periods of low rainfall the pollutants will settle to the bottom of the siltation system and will not be dispersed evenly. This cycle of low rainfall when followed by heavy rainfall, such as occurs in July, will cause the pollutants to be rapidly discharged from the system into the basin of the lake, either in a dissolved form or a free form, causing an unreasonable dilatorious effect to water quality and creating possible turbidity. The confined nature of the proposed channel which empties into the lake will promote scouring because the water is coming out in a more confined area than the natural access allows at present. In addition, the flow velocity in the secondary siltation system is not strong enough to flush out the pollutants in an efficient manner. Finally, channelization promoted by the system would remove a certain percentage of the biological treatment that occurs in the natural intermittent stream, thereby introducing a greater quantity of pollutants into the lake and reducing oxidation that this biological treatment and natural course of the intermittent stream bed now provides. The project, as contemplated, is very similar in its nature to the canal system in Dunns Creek, a body of water adjacent to Crescent Lake. A study conducted on that canal system revealed a very poor quality of dissolved oxygen, which falls below the water quality standards for Class III waters. (A copy of this report may be found as Respondent's Exhibit No. 20 admitted into evidence.) These are the same standards that would apply to Crescent Lake. In addition, there is a lack of flushing and the development of aquatic weeds deterimental to the fish and invertebrates located in the area of the Dunns Creek canals. Therefore, a similar problem could be expected in the project now under consideration. If the project were completed, the excavation of the material would cause disruption of the sediment and water quality degradation if precipitation occurred during the excavation. Efforts at turbidity control would not protect against a heavy rain and the maturely vegetated stream bed and productive littoral vegetation and substrates would be lost. The long term effects of the project would cause degradation of the water quality and a loss of fish and wildlife resources in the impact area. The filtrative assimilative capacity provided by the algae, shrubs, trees and associated substrates involved in the process of absorption and in aerobic bacterial metabolism, would be eliminated by the project and replaced by an intermittently flushed, highly nutrified shallow water lagoon and canal. Pollutants associated with boat operations would further compound the water quality problems and perpetual sediment disruption would occur because of a natural result of shallow water maintenance and use of the system. Siltation and periodic discharge of degraded basin water into the littoral zone of the lake would adversely effect the productive potential and the habitat potential offered by this area in its present form. Based upon a full assessment of the project, it is established that there would be increased and harmful erosion, shoaling of the channel and the creation of stagnant areas of water. It would also cause an interference with the conservation of fish, marine and wildlife to an extent that is contrary to the public interest. It would promote the destruction of natural marine habitats, grass flats suitable as nurseries or feeding grounds for marine life and established marine soils suitable for producing plant growth of a type useful as a nursery or feeding ground for marine life or natural shoreline processes to an extent contrary to the public interests. These failings are in direct contravention of Chapter 253, Florida Statutes. The project would be contrary to State Water Quality Standards, as developed pursuant to authority of Chapter 403, Florida Statutes. Thus, the Petitioner has failed to give reasonable assurances that the immediate and long term impacts of the project would not result in a violation of the State Water Quality Standards, as required by Rule 17-4.28(3), Florida Administrative Code.
